Ground beef, cauliflower, onion, and garlic make up the savory base of this hamburger casserole. A layer of non-fat shredded cheddar or mozzarella melts over the top during its 20–25 minutes in the oven.
Ingredients
- 1 lb ground beef
- 1 cup cauliflower florets
- 1 cup non-fat shredded cheese (cheddar or mozzarella)
- 1 small onion, diced
- 1 clove garlic, minced
- 2 tablespoons olive oil
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
Instructions
- Preheat the oven to 350°F (175°C) and grease a baking dish.
- Heat the olive oil in a large skillet over medium heat.
- Sauté the diced onion and minced garlic until fragrant.
- Add the ground beef and cook, breaking it into smaller pieces, until it reaches 160°F (71°C) on a food thermometer.
- Stir in the cauliflower florets, Italian seasoning, salt, and pepper until evenly combined.
- Transfer the mixture to the prepared baking dish and cover it with the shredded cheese.
- Bake for 20–25 minutes, until the cheese is bubbly and golden.
- Cool slightly before serving.
From Skillet to Casserole Dish
Cut or choose cauliflower florets that are similar in size so they cook consistently. Break up large beef clumps and stir the onion and garlic through the meat. Check the temperature rather than relying on color alone. If excess liquid collects in the skillet, avoid transferring it into the baking dish.
Spread the beef-and-cauliflower mixture into a level layer before adding the cheese. This helps the topping melt evenly and makes the casserole easier to portion. Start checking at the beginning of the stated baking range and remove it when the cheese matches the bubbly, golden cue.
