this Recipe

Ingredients:

• For the Ground Beef Layer:
• 2 lbs Ground Beef (80/20 blend recommended for flavor)
• 1 large Onion, chopped
• 2 cloves Garlic, minced
• 1 Green Bell Pepper, chopped
• 1 (28 ounce) can Crushed Tomatoes
• 1 (15 ounce) can Tomato Sauce
• 1 (15 ounce) can Diced Tomatoes, undrained
• 1 teaspoon Dried Oregano
• 1 teaspoon Dried Basil
• 1/2 teaspoon Garlic Powder
• 1/4 teaspoon Red Pepper Flakes (optional, for a little heat)
• Salt and Black Pepper to taste
• 2 tablespoons Olive Oil
• For the Cauliflower “Rice”:
• 1 large head Cauliflower, cut into florets
• 2 tablespoons Olive Oil
• Salt and Black Pepper to taste
• For the Cheese Sauce:
• 1/2 cup (1 stick) Unsalted Butter
• 1/2 cup All-Purpose Flour
• 4 cups Whole Milk
• 1/2 teaspoon Salt
• 1/4 teaspoon White Pepper
• 1/4 teaspoon Nutmeg (optional, but adds a lovely warmth)
• 4 cups (16 ounces) Shredded Cheddar Cheese, divided (reserve 1 cup for topping)
• 1 cup Shredded Mozzarella Cheese, divided (reserve 1/2 cup for topping)
• Optional Toppings:
• Chopped Fresh Parsley
• Green Onions, sliced

Preparing the Ground Beef Layer:

1. Brown the Ground Beef: In a large skillet or Dutch oven, heat the olive oil over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until browned. Drain off any excess grease. It’s important to get a good sear on the beef for maximum flavor. Don’t overcrowd the pan; if necessary, brown the beef in batches.
2. Sauté the Vegetables: Add the chopped onion and green bell pepper to the skillet with the browned beef. Cook until the vegetables are softened, about 5-7 minutes. Stir frequently to prevent burning. The onions should become translucent and the peppers slightly tender.
3. Add Garlic and Spices: Add the minced garlic, dried oregano, dried basil, garlic powder, and red pepper flakes (if using) to the skillet. Cook for another minute, until fragrant. Be careful not to burn the garlic, as it can become bitter.
4. Simmer the Sauce: Pour in the crushed tomatoes, tomato sauce, and diced tomatoes (undrained). Season with salt and black pepper to taste. Bring the mixture to a simmer, then reduce the heat to low, cover, and let it simmer for at least 20 minutes, or up to an hour, stirring occasionally. The longer it simmers, the more the flavors will meld together. This step is crucial for developing a rich and flavorful sauce.

Preparing the Cauliflower “Rice”:

1. Pulse the Cauliflower: Working in batches, pulse the cauliflower florets in a food processor until they resemble rice. Be careful not to over-process, or you’ll end up with cauliflower puree. You can also use a box grater to grate the cauliflower into rice-sized pieces if you don’t have a food processor.
2. Sauté the Cauliflower Rice: Heat the olive oil in a large skillet over medium heat. Add the cauliflower rice and cook, stirring occasionally, until it’s tender-crisp, about 5-7 minutes. Season with salt and black pepper to taste. Don’t overcook the cauliflower, as it will become mushy in the casserole. You want it to retain some texture.

Making the Cheese Sauce:

1. Melt the Butter: In a large saucepan, melt the butter over medium heat.
2. Whisk in the Flour: Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux. The roux should be smooth and pale golden in color. This step is important for thickening the sauce.
3. Gradually Add the Milk: Gradually whisk in the milk, about 1/2 cup at a time, ensuring each addition is fully incorporated before adding more. This will prevent lumps from forming. Continue whisking until the mixture is smooth.
4. Simmer and Thicken: Bring the mixture to a simmer over medium heat, stirring constantly. Reduce the heat to low and continue to simmer, stirring occasionally, until the sauce has thickened enough to coat the back of a spoon, about 5-7 minutes.
5. Season the Sauce: Remove the saucepan from the heat and stir in the salt, white pepper, and nutmeg (if using).
6. Melt the Cheese: Add 3 cups of the shredded cheddar cheese and 1/2 cup of the shredded mozzarella cheese to the sauce. Stir until the cheese is completely melted and the sauce is smooth and creamy. Make sure the cheese is fully melted before proceeding to the next step.

Assembling the Casserole:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Layer the Ingredients: Spread the cauliflower rice evenly in the bottom of a 9×13 inch baking dish.
3. Add the Ground Beef Layer: Pour the ground beef mixture over the cauliflower rice, spreading it evenly.
4. Pour the Cheese Sauce: Pour the cheese sauce over the ground beef layer, ensuring it covers the entire surface.
5. Top with Cheese: Sprinkle the remaining 1 cup of shredded cheddar cheese and 1/2 cup of shredded mozzarella cheese evenly over the cheese sauce.
6. Bake the Casserole: Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden brown.
7. Let it Rest: Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the casserole to set slightly and makes it easier to slice.
8. Garnish and Serve: Garnish with chopped fresh parsley and sliced green onions (if desired). Serve hot.

Now, let’s talk variations! Feel free to get creative and customize this recipe to your liking. Want to add more vegetables? Toss in some chopped broccoli, bell peppers, or mushrooms. Looking for a spicier kick? Add a pinch of red pepper flakes or a dash of hot sauce to the ground beef mixture. You could even swap out the cheddar cheese for a different variety, like Monterey Jack or Gruyere, for a unique flavor profile. For those watching their carbs, consider using almond flour or coconut flour in the cheese sauce for a lower-carb alternative. You can also substitute the ground beef with ground turkey or chicken for a leaner option.

One of my favorite variations is to add a layer of crispy fried onions on top before baking. It adds a delightful crunch and a savory sweetness that takes the casserole to the next level. Another fun idea is to mix in some cooked bacon bits for an extra smoky flavor. The possibilities are endless!
