Ingredients You’ll Need

These ingredients might look simple, but they each play a key role in creating the creamy, spicy, and savory notes that make this casserole so special. From the tender chicken to the crispy bacon topping, every element matters.

• Chicken breasts, 3 to 4 boneless, skinless, cubed: The hearty base providing protein and a mild flavor that soaks up all the creamy goodness.
• Garlic powder, ½ tablespoon: Adds a subtle pungency that deepens the savory profile of the dish.
• Cream cheese, 8 ounces softened: Creates a rich, velvety sauce that holds everything together.
• Heavy cream, ½ cup: Enhances the creaminess and adds luxurious texture.
• Jalapeno peppers, 5 to 6 seeded and diced: Bring the signature kick that brightens and balances the richness.
• Sharp cheddar cheese, 2 cups shredded: Delivers a tangy, melty topping with vibrant color.
• Bacon, 6 slices chopped: Crisps up beautifully on top, adding a smoky crunch.

How to Make Keto Jalapeno Popper Casserole

Step 1: Prep Your Oven and Pan

Start by preheating your oven to 375 degrees Fahrenheit, which ensures the casserole cooks evenly and the cheese melts perfectly. Then, grab a 9 by 13-inch casserole dish and give it a good spray with nonstick cooking spray—this makes clean-up easier and prevents sticking.

Step 2: Layer the Chicken

Place your cubed chicken breasts in a single layer at the bottom of the casserole dish, making sure to leave a little space between pieces. This lets the heat circulate around each cube, helping them cook through beautifully while soaking up the creamy sauce you’ll pour over next.

Step 3: Make the Creamy Sauce

In a bowl, mix together the softened cream cheese, heavy cream, and garlic powder until smooth. This blend is the heart of your casserole’s luscious texture and deep flavor. Pour it evenly over the chicken, coating every piece in that dreamy, creamy goodness.

Step 4: Add Heat and Cheese

Sprinkle the diced jalapenos evenly over the cream-covered chicken. Their spicy, fresh bite cuts through the richness perfectly. Then generously layer the shredded sharp cheddar on top. This cheese will bubble and brown in the oven, creating that irresistible golden crust you’ll love.

Step 5: Bake and Finish with Bacon

Bake your casserole for 40 to 45 minutes or until the chicken is fully cooked and the cheese is bubbly and golden. When it comes out of the oven, immediately sprinkle the chopped bacon slices on top. The warm casserole will soften them slightly while keeping their smokiness front and center.

How to Serve Keto Jalapeno Popper Casserole

Garnishes

To bring even more flavor to your Keto Jalapeno Popper Casserole, consider garnishing with fresh herbs like chopped cilantro or green onions. A dollop of sour cream or a few slices of avocado also add creamy freshness that complements the spicy cheese and bacon beautifully.

Side Dishes

This casserole shines as the star, so keep sides simple with fresh salads, steamed low-carb veggies, or cauliflower rice. The bright, crisp textures of these add a refreshing contrast to the casserole’s rich creaminess and bold flavors.

Creative Ways to Present

For a fun twist, serve scoops of this casserole in crisp lettuce cups or alongside crunchy keto-friendly crackers. You can also make individual servings in small ramekins for a charming presentation that’s perfect when entertaining friends or family.

Make Ahead and Storage

Storing Leftovers

Got leftovers? No worries! Store your Keto Jalapeno Popper Casserole in an airtight container in the refrigerator for up to 3 days. This allows the flavors to meld even more, sometimes making it taste better the next day.

Freezing

If you want to save some for later, this casserole freezes very well. Portion it into freezer-safe containers and freeze for up to 2 months. Just thaw overnight in the fridge before reheating to retain its creamy texture.

Reheating

Reheat leftovers in the oven at 350 degrees until warm and bubbly, or use a microwave for a quick fix, though the oven better preserves the original texture and melty cheese charm.

FAQs

Can I use different types of cheese in Keto Jalapeno Popper Casserole?

Absolutely! While sharp cheddar is classic, feel free to mix in mozzarella for extra meltiness or pepper jack for added spice. Just keep the overall cheese amount similar to maintain the texture.

How spicy is this casserole? Can I adjust the heat?

The casserole has a moderate kick from the jalapenos but nothing overwhelming. You can easily dial the heat up by using more jalapenos or leave the seeds in. For milder tastes, reduce the number of jalapenos or swap for milder peppers.

Is it necessary to seed the jalapenos?

Seeding helps control the spice level and prevents the casserole from becoming too hot. However, if you enjoy more heat, you can leave some seeds in for added intensity.

Can I substitute the chicken breasts?

Chicken thighs work well here if you prefer darker meat, offering even more juiciness. Just make sure to adjust cooking time slightly to ensure they’re cooked through.

What makes this recipe keto-friendly?

This casserole avoids high-carb ingredients like breading or starchy fillers, focusing on proteins, fats, and low-carb veggies, making it perfect for a ketogenic diet.
