This cheesy ground beef and cauliflower casserole combines lean protein and nutrient-rich vegetables to create a comforting meal that comes together quickly. It offers a great way to enjoy a satisfying dinner with a flavorful mix of spices, fresh veggies, and melted sharp cheddar cheese. This casserole is perfect for busy weeknights when you want something hearty but not complicated.
I first made this casserole on a chilly evening when I wanted something warm and filling. It quickly became a family favorite because everyone loves the cheesy crust and the mix of spicy and tangy flavors from the jalapeños.
Ingredients
- Extra-virgin olive oil: for sautéing and adding richness
- Chopped onion: to build a sweet and savory base
- Green bell pepper: adds freshness and a mild bite; choose firm peppers with shiny skin
- Lean ground beef: for protein without excess grease; look for 93 percent lean for best results
- Bite-size cauliflower florets: bring fiber and antioxidants; fresh or pre-cut is fine but chop smaller if needed
- Minced garlic: to boost flavor and aroma
- Chili powder: for warmth and a touch of heat; use fresh for best flavor
- Ground cumin: adds earthy depth
- Dried oregano: provides a herbal note
- Salt: to enhance all the flavors
- Ground chipotle: gives smoky heat, so add carefully if you prefer less spice
- No-salt-added petite diced tomatoes: add moisture and a touch of acidity
- Extra-sharp Cheddar cheese: for a rich, tangy topping; freshly shredded is best for melt and flavor
- Sliced pickled jalapeños: add tang and a mild spicy kick; adjust quantity to taste
Step-by-Step Instructions
- Sauté the Vegetables:
- Heat olive oil in a large broiler-safe skillet over medium heat. Add chopped onion and bell pepper and cook, stirring occasionally, until softened and fragrant, about 5 minutes. This creates a flavorful base for the casserole.
- Brown the Beef and Cook Cauliflower:
- Add lean ground beef and cauliflower florets to the skillet. Break the beef into small pieces as it cooks. Continue stirring until the beef is no longer pink and cauliflower begins to soften, about 5 to 7 minutes.
- Add Spices and Garlic:
- Stir in minced garlic, chili powder, cumin, oregano, salt, and ground chipotle. Cook for about 1 minute until the spices are fragrant, ensuring the flavors bloom.
- Simmer with Tomatoes:
- Pour in diced tomatoes with their juices. Bring the mixture to a simmer and cook, stirring occasionally, until the liquid reduces slightly and the cauliflower is tender, about 3 minutes.
- Add Cheese and Jalapeños:
- Remove the skillet from heat. Sprinkle shredded Cheddar evenly over the beef and cauliflower mixture, then top with sliced pickled jalapeños.
- Broil Until Golden:
- Place the skillet under the broiler set to high on the upper oven rack. Broil for 2 to 3 minutes or until the cheese is melted and browned in spots. Watch carefully to avoid burning.

I love the sharp Cheddar cheese in this dish because it melts beautifully and adds a satisfying richness. One winter, I served this casserole to my family after a snowstorm, and it was the perfect cozy meal that warmed us up from the inside out.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave to maintain the cheese’s texture. This casserole also freezes well; thaw overnight in the fridge before reheating.
Ingredient Substitutions
Lean ground turkey or chicken can replace ground beef for a lighter version without sacrificing protein. You can swap green bell pepper for red or yellow to change the flavor and add sweetness. If you want less spice, omit the pickled jalapeños or reduce the chipotle powder.
