  • Diced Jalapeños: 4 oz canned, drained (the star of the show!).

Step-by-Step Cooking Instructions

1. Prep Your Kitchen

Start by preheating your oven to 350°F (175°C). Take a 9×13 inch baking dish and lightly grease it so your casserole doesn’t stick to the bottom.

2. Brown the Beef

Place a large skillet over medium heat and cook your 1 lb of ground beef. Once it’s fully browned and no pink remains, be sure to drain off any excess fat.

3. Mix the Creamy Base

Grab a medium mixing bowl. Combine your softened cream cheese, mayonnaise, garlic powder, onion powder, paprika, salt, and pepper. Stir this mixture until it becomes completely smooth and luscious.

4. Fold in the Flavor

Next, it’s time to add the good stuff! Stir the drained jalapeños, 1/2 cup of the cheddar, and 1/2 cup of the mozzarella directly into your cream cheese mixture.

5. Combine and Assemble

Add your browned ground beef to the bowl, mixing well until the meat is fully coated in the spicy, cheesy sauce. Pour this mixture into your greased baking dish, spreading it out into a flat, even layer.

6. Top with Cheese and Bake

Sprinkle the remaining 1/2 cup of cheddar and 1/2 cup of mozzarella evenly over the top. Pop the dish into the oven and bake for 25 to 30 minutes. You’ll know it’s done when the cheese is beautifully melted, bubbly, and slightly golden brown around the edges.

7. Garnish and Serve

Once you pull it out of the oven, let the casserole rest for about 5 minutes. Top it off with fresh chopped green onions, serve warm, and watch it disappear!
