Cauliflower rice and beef casserole is a hearty, low-carb comfort food made with seasoned ground beef, cauliflower rice, vegetables, and melted cheese. It’s a simple, one-pan dish perfect for weeknight dinners or meal prep.

Ingredients

  • 1 lb ground beef
  • 3 cups cauliflower rice (fresh or thawed from frozen)
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 1 bell pepper, diced
  • 1/2 cup tomato paste or 1 cup diced tomatoes
  • 1 tbsp Italian seasoning or taco seasoning
  • Salt and pepper, to taste
  • 1 1/2 cups shredded cheese (cheddar, mozzarella, or blend)
  • 1 tbsp olive oil or butter
  • Optional toppings: chopped parsley, sour cream, green onions

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a large skillet, heat olive oil over medium heat. Sauté onion and garlic until softened.
  3. Add ground beef and cook until browned, breaking it apart. Season with salt, pepper, and seasoning mix.
  4. Stir in diced bell pepper and tomato paste or tomatoes. Simmer for a few minutes.
  5. Add cauliflower rice and mix well. Cook for 2–3 minutes to reduce excess moisture.
  6. Transfer mixture to a greased baking dish and top with shredded cheese.
  7. Bake for 20–25 minutes, until cheese is melted and bubbly.
  8. Let rest for a few minutes before serving. Garnish with optional toppings.

Notes

  • Use well-drained cauliflower rice to avoid a watery casserole.
  • Make it ahead and refrigerate unbaked for up to 24 hours.
  • Great with ground turkey or chicken for a lighter option.
  • Freezes well for up to 2 months — thaw overnight before reheating.
  • Add extra veggies like spinach or corn for variation.
