Instructions
Step 1: Cook the Ground Beef
Heat a large pot over medium heat. Add butter or olive oil, then the ground beef. Cook until browned, breaking it apart with a spoon. Drain excess grease if needed.
Step 2: Sauté Aromatics
Add diced onion and cook 2–3 minutes until softened.
Stir in minced garlic and cook 30 seconds until fragrant.
Step 3: Add Seasonings
Sprinkle in salt, pepper, paprika, parsley/Italian seasoning, and optional red pepper flakes. Stir well so the spices coat the beef.
Step 4: Add Cauliflower & Broth
Add chopped cauliflower florets to the pot.
Pour in the beef broth and bring to a gentle boil.
Reduce heat, cover, and simmer 12–15 minutes until cauliflower is tender.
Step 5: Make It Creamy
Add softened cream cheese and stir until fully melted and smooth.
Pour in heavy cream and simmer on low.
Step 6: Add Cheeses
Add shredded cheddar (and mozzarella if using) into the soup.
Stir until melted and the soup becomes thick, rich, and creamy.
Step 7: Adjust & Serve
Taste and adjust seasoning.
Serve hot, topped with bacon bits, cheddar, green onions, sour cream, or chives.
Additional Notes
- Soup will thicken as it cools due to cheese. Add more broth if needed.
- For extra-tender cauliflower, simmer 5 minutes longer.
- Adding mozzarella makes it extra stretchy and luxurious.
