Ingredients
Scale
- 1 1/2 lbs. ground beef
- 2 T olive oil
- 1 lb. mushrooms, washed, drained dry, and cut into quarters
- 1 onion, chopped small
- 4 cups cauliflower rice
- 1 tsp. steak seasoning
- salt and fresh-ground black pepper to taste
- 1 cup grated Mozzarella
- 1 tsp. Better Than Bouillon Beef Base mixed with 1/4 cup water
- 1 cup sour cream
- 1/2 cup mayo
- 1/4 cup freshly grated Parmesan cheese
- 1/2 tsp. steak seasoning
Instructions
- Preheat oven to 375F/190C. Spray a large glass or ceramic casserole dish with non-stick spray or brush with a little olive oil.
- Mix the Better Than Bouillon Beef Base with 1/4 cup water; then simmer the mixture on the stove until it’s reduced to 1 tablespoon thick stock. Let it cool.
- Heat a couple of teaspoons olive oil in a large heavy frying pan and cook the beef over medium-high heat until browned. Put browned beef in the casserole dish.
- While beef browns, wash mushrooms and let them drain well.
- Chop up the cauliflower and pulse in the food processor to make cauliflower rice if not using packed cauliflower rice.
- Cut drained mushrooms into quarters. In the frying pan, cook mushrooms until they have lost all their liquid and are slightly browned. Add mushrooms to the casserole dish.
- Mix the sour cream and mayo, then add the cooled and reduced stock and stir together.
- While mushrooms cook, chop the onion. Heat oil in the frying pan if needed, add onions, and cook until softened and starting to brown.
- Add cauliflower rice, 1 tsp. steak seasoning, salt, and pepper to the frying pan with the onions. Cook for about 3 minutes or until cauliflower is partly cooked.
- Add the onion-cauliflower rice mixture to the casserole dish and gently combine all ingredients.
- Mix the 1 cup grated Mozzarella, Parmesan, and 1/2 tsp. steak seasoning into the mayo-sour cream mixture.
- Gently mix the sauce into the cauliflower rice-ground beef mixture, patting it down.
- Top the casserole with 1 cup grated Mozzarella.
- Bake casserole for 30-40 minutes or until bubbling hot and the top is lightly browned.
- Serve hot. Leftovers can be kept in the fridge for at least a week.
Notes
- If using pre-packaged cauliflower rice, skip the processing step.
- This casserole reheats well in the microwave or on the stove.
- Substitute other types of cheese if desired.
- Try adding vegetables like spinach or bell peppers for extra nutrition.
