By utilizing riced cauliflower as a nutrient-dense base, this dish absorbs the savory juices of the ground beef and diced tomatoes. The inclusion of sour cream in the filling creates a creamy, melt-in-your-mouth texture that balances the zesty taco seasonings perfectly.

Ingredients

• 1 lb (450 g) ground beef (85% lean)
• 1 tbsp olive oil
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 1 bell pepper (red or green), diced
• 3 cups (350 g) riced cauliflower (fresh or frozen)
• 1 (10 oz/280 g) can diced tomatoes with green chilies, drained
• 2 tbsp taco seasoning (sugar-free, homemade or store-bought)
• ½ tsp salt
• ¼ tsp black pepper
• 1 cup (110 g) shredded cheddar cheese
• 1 cup (110 g) shredded Monterey Jack cheese
• ½ cup (120 ml) sour cream
• Optional: Sliced green onions, chopped cilantro, diced avocado

Instructions

Step 1

Preheat the oven to 375°F (190°C).

Step 2

Heat olive oil in a large skillet over medium heat. Add the onion and bell pepper, sauté for 3–4 minutes until softened.

Step 3

Add garlic and cook for 1 minute until fragrant.

Step 4

Add ground beef and cook, breaking up the meat, until browned and cooked through—about 5–6 minutes. Drain excess fat if necessary.

Step 5

Stir in taco seasoning, salt, pepper, and diced tomatoes with green chilies. Cook for 2 minutes.

Step 6

Add riced cauliflower and cook for another 3–4 minutes until just tender. Remove from heat.

Step 7

Stir in half of the cheddar and Monterey Jack cheeses, and the sour cream until well combined.

Step 8

Transfer the mixture to a greased 9x13-inch (23x33 cm) casserole dish. Sprinkle the remaining cheeses evenly over the top.

Step 9

Bake for 15–18 minutes, or until the cheese is melted and bubbly.

Step 10

Let cool for 5 minutes. Garnish with green onions, cilantro, and avocado if desired. Serve hot.

Zusatztipps für die Zubereitung

To ensure the best texture, make sure to drain the diced tomatoes and green chilies thoroughly before adding them to the skillet. Cooking the cauliflower rice just until tender prevents it from becoming mushy during the baking process.

Varianten und Anpassungen

You can easily swap the ground beef for ground turkey or chicken if you prefer a leaner protein. For those who enjoy extra spice, try adding a diced jalapeño along with the onions and bell peppers.

Serviervorschläge

Top the hot casserole with fresh avocado, cilantro, and sliced green onions for a burst of freshness. This dish pairs beautifully with a crisp, dry white wine or sparkling water with a fresh lime wedge.
