How to Make Ground Beef and Cauliflower Rice Casserole
Preheat your oven to 375°F (190°C). Prepare your baking dish by lightly greasing it with cooking spray.
Sautéing the Vegetables: In a large skillet over medium heat, add a drizzle of olive oil and toss in the chopped onions. Cook until they become translucent and fragrant, about five minutes. Add minced garlic and stir until aromatic but not burnt.
Browning the Beef: Increase heat slightly and add ground beef into the skillet. Break it apart with a wooden spoon as it cooks, allowing it to brown evenly. Season generously with salt, pepper, and Italian herbs while stirring occasionally until cooked through.
Mixing It All Together: Once the beef is browned, fold in the cauliflower rice and pasta sauce, combining everything until evenly coated. Allow this mixture to simmer on low for about five minutes so the flavors meld together beautifully.
Topping It Off with Cheese: Transfer your delicious mixture into the greased baking dish and sprinkle shredded cheese generously on top. The golden melted cheese awaits!
Baking to Perfection: Place your casserole in the preheated oven and bake for about 25-30 minutes until bubbly and golden brown on top. Your kitchen will smell divine during this time!
Now all that’s left is serving this delightful Ground Beef and Cauliflower Rice Casserole hot from the oven, garnished with parsley if you’re feeling fancy!
