Ingredients

  • Chicken or vegetable broth (low sodium preferred)
  • Tomato paste or crushed tomatoes
  • Coconut milk or heavy cream
  • Cooked shredded chicken or turkey
  • Ground beef or turkey (browned and drained)
  • Dried lentils or canned beans (black beans, chickpeas – pre-cooked)
  • Firm tofu or tempeh (for vegetarian options)
  • Carrots, diced
  • Celery, thinly sliced
  • Onions, diced
  • Garlic cloves, minced
  • Spinach or kale
  • Frozen peas or corn kernels
  • Brown rice or quinoa (pre-cooked)
  • Egg noodles, small pasta shapes, or ramen noodles (cooked and drained)
  • Barley or couscous
  • Salt and pepper
  • Smoked paprika or chili powder
  • Fresh or dried herbs like thyme, parsley, or rosemary
  • Grated Parmesan or sharp cheddar (optional)

Instructions

  1. Preheat your thermos by filling it completely with boiling water and letting it sit for 5 minutes.
  2. In a medium saucepan, heat 1 tablespoon olive oil over medium heat. Add 1/2 cup diced onions and 1/2 cup diced carrots. Sauté until softened, about 5 minutes.
  3. Stir in 2 minced garlic cloves and cook until fragrant, about 1 minute, being careful not to burn the garlic.
  4. Pour in 2 cups chicken or vegetable broth. Stir in 1 tablespoon tomato paste, 1/2 teaspoon smoked paprika, salt, and pepper to taste. Bring to a gentle boil.
  5. Add 1 cup cooked shredded chicken and 1/2 cup diced celery. Reduce heat and simmer for 10 minutes to meld flavors.
  6. If using, stir in quick-cooking noodles or pre-cooked grains and heat through for 5-7 minutes.
  7. Stir in a handful (about 1 cup) of fresh spinach or kale and cook just until wilted, about 2 minutes.
  8. Adjust consistency by adding broth or water if too thick, or simmer longer if too thin.
  9. Drain the preheated water from your thermos and immediately pour in the hot soup or stew, filling it almost to the top.
  10. Seal the thermos tightly and store upright until ready to eat. The meal will stay warm for 4–6 hours.

Notes

Preheat your thermos with boiling water for at least 5 minutes before filling to keep food hot longer. Use thicker soups or add grains/beans to maintain heat. Slightly undercook pasta or grains to avoid mushiness. Seal thermos tightly to prevent heat loss. Avoid watery vegetables like zucchini to prevent sogginess.
