Ingredients
Scale
Vegetables and Dairy
- 2 tbsp butter
- 3/4 cup chopped onion
- 3/4 cup chopped celery
- 2 cups cauliflower rice (fresh or frozen)
- 1 cup shredded Monterrey Jack cheese
- 1 cup shredded sharp cheddar cheese
- 4 oz canned green chiles, drained
- 1/2 cup sour cream (full fat)
- 1/2 cup heavy cream
Seasonings
- 1 1/2 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp granulated garlic
Instructions
- Preheat and Prepare Pan: Preheat your oven to 325°F (163°C). Grease an 8×8 inch baking pan with butter or cooking spray and set aside.
- Cook Cauliflower Rice: If using frozen cauliflower rice, cook it according to package instructions, typically about 3 minutes. If using fresh cauliflower rice, steam it on the stovetop or microwave for 3-4 minutes until just tender. Press the cooked cauliflower rice between paper towels to remove excess moisture, ensuring the casserole doesn’t become watery, then set aside.
- Sauté Vegetables and Reduce Cream: Melt butter in a medium sauté pan over medium-high heat. Add chopped celery and onions, cooking for 5-7 minutes until tender. Reduce heat to medium, add the heavy cream, and stir constantly to reduce the cream by half until it becomes thick and creamy. Remove from heat and set aside.
- Combine Ingredients: In a large bowl, mix together the prepared cauliflower rice, half of the Monterrey Jack and cheddar cheeses (½ cup each), green chiles, sour cream, sautéed vegetable and cream mixture, salt, black pepper, and granulated garlic. Stir until everything is thoroughly combined.
- Assemble and Bake: Spread the mixture evenly into the prepared baking pan. Sprinkle the remaining cheese evenly over the top. Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and cheese on top is melted and slightly golden.
- Serve: Remove from the oven and allow to cool slightly before serving. Enjoy your creamy, cheesy cauliflower casserole!
Notes
- Ensure to remove excess moisture from cauliflower rice to avoid a watery casserole.
- Using full-fat sour cream and heavy cream gives the casserole a rich and creamy texture.
- You can substitute the cheeses with other similar melting cheeses if preferred.
- For a spicier version, add a pinch of cayenne pepper or use diced jalapeños instead of green chiles.
- This casserole can be prepared in advance and baked before serving.
