Instructions
- Step 1: Preheat oven to 350°F (175°C). Dice bell peppers into 1/4-inch pieces, then heat 1 tbsp olive oil in a skillet over medium heat until hot. Add peppers and cook for 6-7 minutes until softened but still crisp-tender.
- Step 2: Add ground beef to the skillet, breaking it apart with a spoon, and cook for 8 minutes until browned; drain excess fat. Stir in diced tomatoes, cumin, cayenne, and onion powder, then cook for 2 minutes until flavors meld.
- Step 3: Whisk heavy cream and 1/2 cup cheddar in a bowl until smooth, then pour over the beef mixture. Stir until evenly distributed and the sauce thickens slightly.
- Step 4: Transfer to a greased 8x8-inch baking dish, top with remaining 1/2 cup cheddar, and bake uncovered for 22-25 minutes until the cheese is golden and bubbly.
