Preparation Phase & Tools to Use
Before diving into the cooking process, it’s crucial to set up your kitchen correctly. Begin by ensuring your workspace is clean and organized, with all ingredients and tools easily accessible. You’ll need a reliable skillet for sautéing the ground beef mixture and a 9×13-inch baking dish for the casserole. A wooden spoon or spatula will help when stirring ingredients, while a sharp knife is necessary for dicing the onion and mincing the garlic.
Precision in cooking starts with having the right tools at your disposal. Make sure to have measuring spoons to accurately portion out the Italian seasoning, paprika, and butter. A good quality cheese grater will be essential if you’re using a block of cheese instead of pre-shredded options. Having these tools upfront will streamline your cooking process, ensuring a stress-free culinary adventure.

Ingredients
- 1 tbsp olive oil
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 lb lean ground beef
- 1 tsp Italian seasoning
- ½ tsp sweet paprika
- Salt and black pepper, to taste
- 6 oz baby spinach
- 10 oz frozen cauliflower rice, cooked
- 1 cup sour cream (or plain yogurt)
- 1 tbsp butter, softened
- ½ tsp dried basil
- 2–3 tbsp milk (optional, if needed for mixing)
- 8 oz shredded Italian blend cheese (or any cheese you like)
Instructions
Step 1: Preheat the Oven
Begin by heating your oven to 375°F (190°C). As your oven reaches this temperature, it will ensure your casserole bakes evenly and thoroughly, providing the perfect texture.
Step 2: Cook the Beef Mixture
In a large skillet, heat the olive oil over medium-high heat. Add the diced onion, sautéing it for about 2 minutes until it becomes translucent. Introduce the minced garlic and stir for an additional 20 seconds until fragrant. Next, incorporate the ground beef along with the Italian seasoning, paprika, salt, and pepper. Cook the beef until browned, breaking it apart into smaller chunks as it cooks. After browning, add the baby spinach, cooking until wilted. Finally, remove the mixture from heat and drain any excess liquid to avoid wateriness in your casserole.
Step 3: Mix the Cauliflower Base
In a 9×13-inch baking dish, combine the cooked cauliflower rice with sour cream, softened butter, and dried basil. Stir until you achieve a creamy consistency. If the mixture appears a bit thick, add a splash of milk to loosen it up.
Step 4: Assemble the Casserole
Now, merge the beef-spinach mixture with the creamy cauliflower base. Stir to evenly distribute all components. Once well-mixed, spread the mixture uniformly across the baking dish and top it with shredded cheese of your choice, ensuring it covers the mixture completely.
Step 5: Bake & Rest
Bake the assembled casserole uncovered for about 22 to 25 minutes, or until the cheese is bubbling and golden brown. Once baked, allow the casserole to rest for 7 to 10 minutes before slicing. This resting period helps in easy slicing and serving, allowing flavors to meld and the structure to firm up.

Variations
- Protein: Substitute ground beef with ground turkey or chicken for a leaner option. Alternatively, use crumbled tofu for a vegetarian twist.
- Vegetables: Add bell peppers or mushrooms to the beef mixture for a different texture and flavor.
- Spices: Consider adding a pinch of chili flakes for a spicier kick, or try curry powder for an exotic touch.
Cooking Notes
- For a thicker sauce, reduce the amount of milk added to the cauliflower mixture or skip it altogether.
- Ensure the spinach is well-drained to prevent excess moisture in your casserole.
Serving Suggestions
- Pair with a fresh garden salad tossed with olive oil and vinegar dressing for a refreshing contrast.
- Serve alongside garlic bread to soak up the delicious casserole juices.
Tips
- Use pre-cooked cauliflower rice to save time on preparation. Simply steam or microwave it according to package instructions.
- Taste and adjust seasonings after mixing the casserole before baking, if desired.
