Why casseroles are ideal for healthy weeknight dinners
- One-dish cooking = less cleanup.
- Easily scalable for meal prep or family dinners.
- Great for stretching proteins and using seasonal produce.
- Can be balanced in macros: protein + fiber + healthy fats.
Quick tips for healthier casseroles
- Use Greek yogurt or low-fat milk instead of heavy cream.
- Bulk up with beans, lentils, or whole grains to increase fiber and satiety.
- Roast vegetables first for deeper flavor with less added fat.
- Use whole-grain pasta, brown rice, or quinoa as your base.
- Keep a portion of lean protein per serving (3–4 oz cooked).
