Ingredients

Instructions

  1. Step 1: Steam 4 cups cauliflower florets until very tender, about 10 minutes, then mash with 3 tbsp unsalted butter, 2 oz cream cheese, 1 tsp salt, and 1/2 tsp black pepper until smooth and creamy.
  2. Step 2: Preheat oven to 375°F.
  3. Step 3: Heat 1 tbsp olive oil in a large skillet over medium heat. Sauté 1 diced small onion and 2 minced garlic cloves for 3-4 minutes until translucent and fragrant.
  4. Step 4: Add 1 lb ground beef to the skillet and cook, breaking up with a spoon, until browned and cooked through, about 6-7 minutes.
  5. Step 5: Stir in 2 tbsp tomato paste, 1/2 cup beef broth, and 1 tsp dried thyme, cooking for 4-5 minutes until the mixture thickens slightly.
  6. Step 6: Transfer the beef mixture to a 9-inch baking dish and spread evenly. Top with the cauliflower mash, smoothing the surface.
  7. Step 7: Sprinkle 1 cup shredded cheddar cheese evenly over the top.
  8. Step 8: Bake for 20 minutes until the cheese is melted and golden brown on top.
