Batch Cooking With a Small Appetite: Cook Once, Eat Well All Week

If you take semaglutide (Ozempic, Wegovy) or tirzepatide (Zepbound, Mounjaro) and cooking has lost its appeal, batch cooking can cover your week in a single session. Cook three four-serving recipes in about two hours, divide them into small containers and freeze half. That way, when hunger does show up, there’s something with protein ready in five minutes.

On names: Ozempic is semaglutide and Mounjaro is tirzepatide, both approved in the US for type 2 diabetes. Wegovy and Zepbound are the same molecules approved for weight management, so I lead with their labels. The full eating plan is in my guide to what to eat on GLP-1 medications.

Why cooking (and eating) gets harder on a GLP-1

The medication changes your appetite, and that changes how you feel about the kitchen.

• Less hunger, less food. The US Wegovy label states that semaglutide decreases calorie intake, and the effects are likely mediated by affecting appetite^[1]. The US Zepbound label says the same of tirzepatide^[2]. The EU prescribing information for Wegovy adds a figure the US label doesn’t give: in a phase 1 trial, energy intake at an eat-as-much-as-you-like meal was 35% lower with semaglutide than with placebo after 20 weeks^[3].Dotted underline: a drug-label fact; hover over it to see the date it was checked.
• Less interest in food. The authors of the 2025 advisory on nutrition and GLP-1 therapy, from four US obesity, nutrition and lifestyle-medicine societies, write that in their practice a substantial number of people become less interested in food. They also list losing interest in a food-related hobby, such as cooking, among the things worth talking through with patients^[4]. That’s clinical experience, not a trial.
• Nausea on a schedule. On the Zepbound label, the majority of nausea, vomiting and diarrhea events occurred during dose escalation and decreased over time^[2]. The US Wegovy label sets its dose-escalation schedule to reduce the risk of digestive side effects^[1], and the EU prescribing information says digestive side effects were mainly seen during dose escalation, and nausea lasted a median of 8 days^[3].

The advisory adds two details that explain why ready-made food helps. Nausea often comes in the morning or after long stretches without eating, and some people get caught in a cycle: they don’t eat because of the nausea, which makes the nausea worse. Vomiting is also more likely after large meals^[4]. A small container that’s already cooked breaks that cycle better than an empty kitchen.

The small-portion method

The idea is simple: cook regular four-serving recipes and divide them into more, smaller containers.

1. Cook four-serving recipes. The ones on this site are already calculated that way.
2. Divide into containers of 150 to 250 g (5 to 9 oz) of food, not counting the soup broth. In practice, 1-cup (8 fl oz, about 240 ml) containers work for the meatballs, and 2-cup (16 fl oz, about 475 ml) containers hold a soup portion with its broth. Four recipe servings fill six to eight small containers. If you fill up quickly, it’s easier to finish a small container than to leave half of a big one.
3. Freeze half. The fridge covers the first 3 or 4 days^[5]; the freezer covers the rest of the week.
4. Label each container with the name and the date. By Thursday, you won’t remember what you cooked on Sunday.

The advisory notes that small, frequent meals may work when hunger and interest in food are low, and that eating protein-rich foods first makes it more likely you’ll get enough^[4]. That’s why all three dishes in this plan have the protein built in, not on the side.

A 2-hour Sunday plan

It’s three recipes from our recipe section, plus two things that barely need the stove. Protein per serving comes from each recipe, calculated from the USDA FoodData Central values in our food pages^[12].

By ingredient weight, each soup container holds about 185 g (6.5 oz) of chicken and vegetables, each meatball container about 150 g (5 oz) of meatballs and sauce, and each lentil container about 210 g (7.5 oz) of lentils and vegetables, plus the broth in both soups.

The times are approximate and assume three burners and a skillet.

• 0:00 to 0:20. All the chopping at once. Chop the onions, carrots, potatoes, bell pepper, zucchini and chayote. Mix the turkey with the egg and breadcrumbs and shape the 16 meatballs.
• 0:20. Pot 1, chicken soup. Put the chicken breast in the pot with the water, onion and garlic, and simmer gently for 20 minutes.
• 0:25. Skillet. Brown the meatballs in half the oil and set them aside.
• 0:35. Pot 2, sauce. Cook the onion and carrot for 5 minutes, add the tomatoes for 10 minutes, then the meatballs, covered, for 15 more.
• 0:45. Back to pot 1. Lift out the chicken and shred it. Add the potato, carrots and chayote for 10 minutes, then the zucchini for 5 more.
• 0:50. Pot 3, lentils. Onion and pepper, vegetables and water for 15 minutes; the canned lentils for 10; the spinach at the end.
• 1:05. The quick things. Boil the edamame for 4 to 5 minutes and hard-boil six eggs. Make the three jars of oats and put them in the fridge.
• 1:25 to 1:50. Divide, cool and store. Wide, shallow containers, labeled and dated. Half in the fridge, half in the freezer.
• 1:50 to 2:00. Clean up.

How the week works. From Sunday to Wednesday you eat from the fridge: three containers of chicken soup, four of meatballs, three of lentils, the oats and the edamame. The freezer holds the other ten containers for Thursday onward. Each evening, move the next day’s food to the fridge to thaw.

A sample day. Oats (20.4 g of protein), chicken soup (14.6 g), two meatballs (14.0 g), edamame (12.4 g) and lentils topped with a chopped hard-boiled egg of 50 g, about 2 oz (15.6 g together): 77.0 g across five small meals. As a general reference, the advisory mentions absolute targets of 80 to 120 g of protein a day, or 1.2 to 1.6 g per kilogram of body weight proposed during active weight loss^[4]. That isn’t a target for you: your number is up to your doctor or dietitian, and you can estimate it with the protein calculator. For more dishes ranked by protein, see the high-protein recipes.

Food safety: cooling, storing, thawing and reheating

These rules come from the USDA Food Safety and Inspection Service, the FDA and the cold food storage chart at FoodSafety.gov:

• Refrigerate within 2 hours of cooking, or within 1 hour when it’s above 90 °F^[6,8].
• Cool it fast. FSIS says to divide large amounts into shallow containers, because a big pot of soup takes a long time to cool. Hot food can go straight into the fridge^[6].
• Fridge at 40 °F (4 °C) or below, freezer at 0 °F (-18 °C). The FDA also says not to pack them so tightly that air can’t circulate^[8], which matters on a Sunday afternoon.
• 3 to 4 days in the fridge for soups, stews and cooked meat or poultry, according to the chart^[5].
• 2 to 3 months in the freezer for soups and stews^[5]. Food kept at 0 °F stays safe indefinitely^[7,8]; that limit is about quality, not safety. (FSIS gives 3 to 4 months for leftovers in general^[6]; I use the chart’s shorter figure for soups.)
• Airtight containers. The FDA recommends tight containers for leftovers and explains that freezer burn is a quality issue, not a safety one^[8].
• Thaw in the fridge, in cold water in a leak-proof bag, or in the microwave. FSIS says never on the counter^[7]. Soups and stews can also be reheated straight from frozen in a saucepan or the microwave; it just takes longer^[6].
• Reheat to 165 °F, measured with a food thermometer, and bring soups and sauces to a rolling boil^[6].

The hard-boiled eggs for the lentils go in the fridge: the chart gives them 1 week and says not to freeze them^[5].

What freezes well and what doesn’t

The left column comes from the freezing tips in our recipes and from the USDA chart^[5]; the right column comes from the list of foods that don’t freeze well from the National Center for Home Food Preservation at the University of Georgia^[9]. These are texture problems, not safety problems. Both soups in this plan contain potato, which gets softer in the freezer: if that bothers you, leave it out of the portions you freeze. For the same reason, the pumpkin and chayote soup is frozen without the yogurt, and the pisto without the eggs.

One more tip from the same center: season lightly before freezing. Garlic, pepper and some herbs get stronger or bitter, and salt loses flavor^[9]. Adjust when you serve.

Cooking for the family when you eat four bites

You don’t need to cook two menus. Cook the same base for everyone and change the portion and the side.

Three ideas that help at home:

• Double one recipe, not three. If the whole household eats meatballs on Sunday, make 32: dinner comes out of one pot and your containers out of the other.
• Set your portion aside before serving. A smaller plate heads off the “finish your plate” comments.
• Broth is your friend. MedlinePlus’s bland diet, which it describes for nausea among other problems, includes soup, especially broth, and cooked vegetables^[10].

If people at the table ask why you’re eating so little, I have a few answers that don’t start a debate in eating out on Ozempic, Wegovy or Zepbound.

Shopping list

For the five preparations in the plan, raw unless noted:

• Protein: 350 g (12 oz) chicken breast, 400 g (14 oz) ground turkey breast, 7 eggs (one for the meatballs and six to hard-boil), 500 g (about 2½ cups) canned lentils, drained, 300 g (11 oz) frozen shelled edamame, 360 g (about 1½ cups) plain nonfat Greek yogurt.
• Vegetables: 370 g (13 oz) carrots, 220 g (8 oz) onions, 400 g (14 oz) potatoes, 200 g (7 oz) zucchini, 150 g (5.5 oz) chayote, 80 g (3 oz) red bell pepper, 100 g (3.5 oz, about 3 cups) fresh spinach, 150 g (5.5 oz) fresh tomato and 500 g (about 2 cups) crushed tomatoes.
• Pantry: 30 g (1 oz) whole-wheat bread for breadcrumbs, 90 g (1 cup) rolled oats, 15 g (3 heaping teaspoons) chia seeds, 9 g (3 teaspoons) sesame seeds, 2 tablespoons olive oil and 1 cup (240 ml) 2% milk.
• Fruit: 180 g (about 1½ cups) raspberries, fresh or frozen, and a lime.
• To taste: garlic, parsley or cilantro, a bay leaf, paprika, cumin, cinnamon, chili powder, salt and pepper.
• Containers: about 20 small freezer-safe containers, 1-cup and 2-cup, plus 3 jars with lids.

Days when you don’t have the energy even for this

Some weeks you won’t have two free hours. Three ways out:

• Just one pot. The chicken soup on its own takes 45 minutes and fills six containers.
• No-cook recipes. Cottage cheese with pineapple (16.0 g of protein, 3 minutes), Greek yogurt with fruit and seeds (16.5 g) or ham roll-ups with queso fresco and cucumber (12.5 g).
• Simple frozen foods. Frozen vegetables, frozen fish or seafood, edamame. According to the FDA, freezing doesn’t reduce nutrients, and there is little change in a food’s protein value^[8]. If you buy frozen meals, compare the protein per package on the Nutrition Facts label.

There are more ideas for small meals in filling snacks on GLP-1 medications, light evening options in the light dinner recipes, and a seven-day plan in the weekly menu planner. To combine fridge containers into a balanced meal, see the Harvard Healthy Eating Plate on Ozempic or Zepbound.

Eating well, not as little as possible

Cooking ahead is about having good food on hand when hunger arrives, not about eating the bare minimum. If you finish a container and want another one, have it.

If food makes you anxious, you skip meals to make up for eating, or controlling what you eat has become the most important thing, talk to a healthcare professional. MedlinePlus describes eating disorders as serious mental health disorders and stresses the importance of seeking help^[11].

And if nausea keeps you from eating or drinking, don’t wait for next Sunday: talk to your prescriber. What tends to sit best is in nausea on GLP-1 medications: what to eat and what to avoid, and the symptom diary helps you explain it at your appointment.

Frequently asked questions

What’s the difference between meal prep and batch cooking?

People use them almost interchangeably. I draw the line like this: batch cooking is cooking several recipes at once; meal prep is having the meals already divided into containers. With a small appetite, it pays to do both: cook in batches and divide into small portions.

How long does cooked food last in the fridge and the freezer?

Soups, stews and cooked meat or poultry: 3 to 4 days in the fridge at 40 °F or below, and 2 to 3 months in the freezer for soups and stews, according to the USDA chart at FoodSafety.gov^[5]. At 0 °F food stays safe indefinitely; those months are about quality^[7,8]. Anything you won’t eat within 3 or 4 days goes in the freezer on day one.

Can I reheat frozen soup without thawing it first?

Yes. FSIS says it’s safe to reheat frozen soups and stews without thawing, in a saucepan or the microwave; it just takes longer. Either way, heat it to 165 °F and bring soup to a rolling boil^[6].

Can I freeze cooked rice or pasta?

You can, but frozen on their own they turn mushy, according to the University of Georgia’s food preservation center^[9]. If texture matters to you, freeze the stew without the side and cook the rice or pasta on the day you eat it.
