Oven-roasted chicken: one batch for several days
Roasted chicken is the most practical meal prep there is: forty minutes of oven time covers your protein needs for lunch for three to four days. The only challenge is that chicken breast dries out easily, and the solution isn't a special recipe, but rather temperature and timing.
The basics: how to avoid drying it out
Poultry meat becomes dry when the protein is cooked for too long. Two things solve almost everything.
Don't overcook it. Chicken breast needs only 25–30 minutes at 190 °C, and thighs need 35–40. It is better to rely not on the clock, but on the juices running clear when pierced in the thickest part.
Salt in advance. Salting 30–40 minutes before roasting—or the night before—noticeably changes the result: the meat retains more moisture. This is a case where the order of operations is more important than the ingredients.
A third, optional step: let it rest for 5–10 minutes after taking it out of the oven before slicing. The juices redistribute, and less of them will end up on the cutting board.
Chicken breast
Ingredients: 2 chicken breasts, salt, pepper, a teaspoon of oil.
Method: Salt half an hour before. Pat dry, brush with oil, and season with pepper. Oven at 190 °C for 25–30 minutes, depending on thickness. Check by piercing.
Estimate: about 165 kcal and 31 g of protein per 100 g of cooked product.
If the breasts are very thick, slice them in half lengthwise—this is more reliable than increasing the cooking time.
Chicken thighs
Ingredients: 6 skinless chicken thighs, salt, pepper, paprika.
Method: Same as above, but 35–40 minutes at 200 °C.
Estimate: about 190 kcal and 25 g of protein per 100 g (skinless).
Thighs are much more forgiving of overcooking than breasts and are tastier for most people. With the skin on, the calorie count increases to approximately 220–230 kcal per 100 g.
Three marinades from pantry staples
| Marinade | Ingredients |
|---|---|
| Yogurt | 3 tbsp thick yogurt, garlic, paprika, salt |
| Lemon-herb | Juice of half a lemon, a spoonful of oil, dried herbs, salt |
| Soy-honey | 2 tbsp soy sauce, a teaspoon of honey, garlic, pepper |
The marinade adds 20–60 kcal per serving—mainly due to the oil and honey. Soy sauce provides a significant amount of salt, so there is no need to add extra salt afterward; how much salt comes from processed foods is analyzed in our article on salt in processed foods.
Half an hour of marinating provides almost the full effect; overnight is better, but not strictly necessary.
Vegetables on the same tray
Zucchini, bell peppers, onions, carrots, broccoli, and cauliflower should be cut into large chunks, drizzled with a spoonful of oil, and placed on the tray. The cooking time matches the thighs; for chicken breasts, it is better to put the vegetables in 10 minutes earlier.
This way, one batch covers both the protein and the side dish, and your plate can be assembled according to the scheme from our article on weekly meal planning.
What to do with the finished product
- Store whole, slice before eating. Sliced meat dries out faster.
- Three to four days in the refrigerator, after that—freeze in portions.
- Reheat covered with a spoonful of water: a microwave without a lid dries food out more than an oven does.
- Use cold in salads. Assembly ideas are in our article on salads without mayonnaise.

Frequently asked questions
- How long should I roast chicken breast?
- 25–30 minutes at 190 °C depending on thickness. It is better to rely on clear juices when pierced in the thickest part, and to slice very thick breasts in half lengthwise.
- Why does the breast turn out dry?
- Most often due to overcooking. It helps to salt it half an hour before baking—the meat retains more moisture—and to let the cooked chicken rest for 5–10 minutes before slicing.
- How many calories and protein are in baked chicken?
- A breast has about 165 kcal and 31 g of protein per 100 g of cooked product, while a skinless thigh has about 190 kcal and 25 g of protein. With the skin, the calorie content of the thigh increases to approximately 220–230 kcal.
- How long should I marinate the chicken?
- Half an hour provides almost the full effect; overnight is better, but not strictly necessary. After a soy sauce marinade, there is no need to add extra salt—there is enough in the marinade.
- How long does roasted chicken keep?
- Three to four days in the refrigerator; after that, it is better to freeze it in portions. It is best to store it as a whole piece and slice it before eating: sliced meat dries out noticeably faster.
