How to batch cook for the AIP elimination diet

Prep is the part of AIP that decides whether you finish it. Here is a method that survives past Wednesday.

The food list is a one-time lesson — a week in, you know what is out. What wears people down is the cooking. Compliant convenience food barely exists, the safe list is narrow, and nobody solo-cooks 21 meals a week for long. Most people who stop AIP do not stop because they lost faith in it. They stop at 6pm on a Wednesday with nothing in the fridge.

Batch cooking is the fix — but not the version of batch cooking most people try first. (Not started yet? How to start the AIP elimination diet covers the week before day one.)

The mistake: batching finished meals

The instinct is to cook one big dish on Sunday. A tray of chicken and squash, six portions, done. It works for about three days. Then you open the fridge, see the same tray, and cannot do it. That is palate fatigue, and it ends protocols just as reliably as an empty fridge does.

The problem is that a finished meal is locked. There is nothing you can do with portion five to make it taste like a different dinner.

Batch components instead, then assemble

Cook parts, not meals. On prep day you make a small set of components. At mealtime you combine them into a plate — two minutes, no cooking. Every plate is built from four slots:

• A protein — roasted chicken thighs, browned ground beef, a couple of seared steaks
• A starchy carb — roasted sweet potato, butternut squash, cassava, plantain
• A vegetable — roasted broccoli, cauliflower, carrots, sautéed greens
• A fat and a flavor — the part that makes it taste like a different meal

Three proteins, two carbs, four vegetables and four flavors is a normal week’s kit. That is far fewer than 21 decisions, and it takes one session.

Combination is not variety

This is the part most prep guides miss. Three proteins times four vegetables looks like twelve dinners. It is not. If every plate is seasoned the same way, it is chicken-and-vegetables twelve times, and your palate knows.

Your tongue tastes flavor, not combinations. So variety has to come from a third axis — the sauce, the herb, the fat, the cooking method:

• Garlic, rosemary, olive oil reads Mediterranean
• Ginger, coconut aminos, scallion greens reads like a stir-fry
• Cilantro, lime, duck fat reads bright and Latin
• Cinnamon and coconut milk turn roasted squash into something almost sweet

Same chicken, same sweet potato, four different dinners. Batch your components plain and flavor them on the plate — that is what keeps a kit from collapsing into efficient monotony.

One note specific to AIP: your flavor options are narrower than they look, because seed spices are out during elimination — cumin, coriander, fennel, mustard, black pepper. What you have is leaf, bark, root and flower: herbs, garlic, ginger, turmeric, cinnamon, clove, citrus, vinegars, coconut aminos. It is more than enough, but it is worth learning the list rather than reaching for a spice blend and hoping — the full elimination food list has every category.

A first prep day, concretely

About 90 minutes, most of it oven time you can walk away from. Get the oven to 425°F first — nearly everything roasts in that range, so trays go in and out while you work on the next thing.

1. Chicken thighs (3–4 lb, bone-in, skin-on). Pat dry, rub with tallow or olive oil and sea salt. Roast 35–40 min until the skin crisps and the internal temperature reads 175°F. Rest 10 minutes, then shred or slice.
2. Ground beef (2 lb). Brown in a hot pan with a spoonful of tallow and salt, breaking it up, 8–10 min until no pink remains.
3. Sweet potato. Cube, toss with olive oil and salt, roast 25–30 min, flipping once, until the edges caramelize.
4. Butternut squash. Peel, seed and cube; toss with olive oil, salt and a little cinnamon. Roast at 400°F for 30–35 min.
5. Broccoli and carrots. Florets and coins, olive oil, salt, roasted at 425°F — broccoli about 20 min, carrots 25–30.
6. Greens last. Kale or chard sautéed in olive oil with garlic, 3–5 min. These keep the least well, so make a smaller batch and redo them mid-week.

Store each component in its own container, not pre-assembled. That is what keeps a plate flexible.

Stock a no-cook shelf too

Batching solves “I don’t feel like cooking.” It does not solve “I need food now” — the moment when you are hungry, tired, and the fridge asks even ten minutes of you. For that you need a shelf of things that take zero prep and no assembly:

Tuna with avocado, sauerkraut and a handful of greens is a complete compliant meal with no cooking and no plan. Keep this shelf stocked as deliberately as you keep the batched components, because it is the one that catches you at the worst moment. It also covers the afternoon gap — if more than about four hours pass between two meals, hunger eventually wins that argument, and it is better to lose it to sardines.

Two prep sessions beat one

The uncomfortable arithmetic: cooked meat keeps three to four days in the fridge, per USDA guidance. A single Sunday prep meant to cover all seven days has you eating week-old chicken by Friday.

Two shorter sessions solve it — Sunday and Wednesday, roughly — while still running off one grocery trip. Buy for the whole week, freeze the second batch’s raw proteins, and move them to the fridge the night before you cook them. Vegetables and starches are more forgiving; it is the protein that sets the schedule.

Reheat cauliflower rice in a hot dry pan rather than a microwave — the microwave makes it wet.

Nothing in that table was cooked after Sunday.
