Short Description

This Keto Jalapeño Popper Casserole is a creamy, cheesy, and slightly spicy dish perfect for a low-carb dinner. Made with ground beef, cream cheese, jalapeños, and plenty of gooey melted cheese, it’s packed with flavor and easy to prepare.

Key Ingredients

• 1 lb ground beef
• 8 oz cream cheese, softened
• 1 cup shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• 4 oz canned diced jalapeños, drained (or fresh jalapeños, diced)
• 1/2 cup mayonnaise
• 1 tsp garlic powder
• 1 tsp onion powder
• 1/2 tsp paprika
• Salt and pepper, to taste
• 1/4 cup chopped green onions, for garnish

Tools Needed

• Large skillet
• Mixing bowls
• 9×13-inch baking dish
• Spatula or wooden spoon
• Oven

Cooking Instructions

Step 1: Cook the Ground Beef

In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it apart as it cooks. Drain any excess grease, then season with garlic powder, onion powder, paprika, salt, and pepper.

Step 2: Make the Creamy Base

Reduce the heat to low and stir in the softened cream cheese until fully melted and combined with the beef. This creates a rich, creamy filling that binds everything together.

Step 3: Add Jalapeños and Cheese

Mix in the diced jalapeños, shredded cheddar, and half of the mozzarella cheese. Stir until everything is well distributed, then remove from heat.

Step 4: Assemble the Casserole

Spread the beef mixture evenly into a greased 9×13-inch baking dish. In a small bowl, whisk together the mayonnaise and remaining mozzarella cheese, then spread it over the top.

Step 5: Bake to Perfection

Bake at 375°F (190°C) for 20-25 minutes, or until the cheese is golden and bubbly.

Step 6: Garnish and Serve

Remove from the oven and let it sit for 5 minutes. Sprinkle chopped green onions over the top, then serve warm.

Mistakes to Avoid & Solutions

If you’re sensitive to spice, start with half the amount and add more as needed.

4. Skipping the cream cheese step

Make sure it’s fully melted into the beef for a smooth and creamy texture.
