🔥 How to Make Cheesy Jalapeño Beef Casserole
This casserole is straightforward, comforting, and fast. Here’s a step-by-step breakdown:
1. Cook the Ground Beef
In a large skillet, cook the ground beef over medium-high heat until browned. Drain excess fat if necessary.
2. Add Aromatics & Jalapeños
Stir in the diced onion and chopped jalapeños. Cook for 3–4 minutes until soft and fragrant. You’ll smell that amazing jalapeño aroma instantly.
3. Add Rotel & Seasonings
Mix in the Rotel, garlic powder, onion powder, chili powder, salt, and pepper. Let everything simmer together for a few minutes so the flavors combine.
4. Make It Creamy
Turn off the heat and stir in the sour cream until fully mixed. The sauce will become creamy, silky, and lightly spicy.
5. Add Your Base (Optional)
If you’re using rice or noodles, fold them in now. This makes the casserole heartier and stretches it further.
6. Layer with Cheese & Bake
Transfer everything to a baking dish. Sprinkle the top with cheddar and pepper jack cheese. Bake at 375°F (190°C) for 20–25 minutes, or until bubbly and golden.
7. Add Fresh Toppings
Once out of the oven, top with sliced green onions or chopped cilantro. It adds the perfect contrast to the rich and creamy base.
