Gathering the ingredients for this dish is a breeze because each one plays a vital role—from packing flavor to adding rich texture and a pleasing color contrast. These essentials work harmoniously to bring your casserole to life.
- Bacon (6 slices, chopped): Adds smoky crunch and richness that blends perfectly with the creamy elements.

- Onion powder (1/2 teaspoon): Enhances flavor complexity with a gentle sweetness.
- Salt and pepper: Balances all flavors beautifully—season to your taste.
- Diced jalapeños (1/2 cup, fresh or pickled): Provides the signature spicy kick that gives this casserole its character.
- Cream cheese (8 ounces, softened): The rich, creamy glue that binds everything together and ensures luscious indulgence.
- Sour cream (1/2 cup): Adds tanginess and moisture, keeping the casserole silky.
- Shredded cheddar cheese (1 cup): Delivers sharpness and melts into a golden, bubbly topping.
- Shredded mozzarella cheese (1/2 cup): Creates that stretchy, gooey texture everyone loves in casseroles.

How to Make Keto Jalapeño Popper Casserole Recipe
Step 1: Prepare and cook bacon
Start by preheating your oven to 375°F (190°C) and greasing a 9×9-inch baking dish to prevent sticking. In a large skillet over medium heat, cook the chopped bacon until it’s deliciously crispy. Once cooked, transfer the bacon to a paper towel-lined plate to drain. Keep 1 tablespoon of the rendered bacon grease in the skillet for added flavor in the next step.
Step 2: Cook the chicken
Next, add the cubed chicken to the skillet with the reserved bacon grease. Season it generously with garlic powder, onion powder, salt, and pepper. Cook the chicken until it’s browned on all sides and cooked through, about 6 to 8 minutes. This ensures the chicken stays juicy and develops a nice sear, which adds an extra layer of flavor.
Step 3: Mix the creamy cheese and jalapeño topping
While the chicken is cooking, combine the softened cream cheese, sour cream, half of the shredded cheddar cheese, mozzarella, Parmesan, and half of the diced jalapeños in a mixing bowl. Stir until smooth and completely blended. This creamy mixture is what makes this casserole sing—each bite is rich, spicy, and irresistibly cheesy.
Step 4: Assemble the casserole
Transfer the cooked chicken to your prepared baking dish. Spread the cream cheese and jalapeño mixture evenly on top, making sure to cover all the chicken pieces. Then sprinkle the remaining cheddar cheese, jalapeños, and cooked bacon over the creamy layer. This combination of toppings will melt and crisp up beautifully in the oven.
Step 5: Bake to perfection
Place the casserole in the preheated oven and bake uncovered for 20 to 25 minutes. The casserole should be bubbly and golden on top when it’s done. This baking time allows all the flavors to meld together and creates a deliciously crispy surface while keeping the inside creamy and tender.
How to Serve Keto Jalapeño Popper Casserole Recipe
Garnishes
For a fresh finish, sprinkle sliced green onions over the hot casserole just before serving. The mild bite and bright green color add a wonderful contrast and elevate the presentation effortlessly.
Side Dishes
This casserole stands strong on its own as a hearty main, but you can balance the rich flavors with light sides like a crisp green salad or steamed low-carb veggies such as asparagus or broccoli. Cauliflower rice also makes an excellent, keto-friendly accompaniment.
Creative Ways to Present
Want to wow your guests? Serve this casserole in individual ramekins or small cast-iron skillets for a charming, rustic look. Alternatively, top with an extra sprinkle of fresh herbs like chopped cilantro or parsley for a pop of color and freshness.
Make Ahead and Storage
Storing Leftovers
Leftovers keep well in an airtight container in the fridge for up to 3 days. When stored properly, the flavors only deepen overnight, making it an ideal meal prep option to enjoy throughout the week.
Freezing
This Keto Jalapeño Popper Casserole Recipe freezes beautifully. Simply assemble the casserole but don’t bake it, cover tightly with foil or plastic wrap, and freeze for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator and then bake as directed, adding a few extra minutes if still slightly frozen.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15 to 20 minutes until warmed through and bubbly. You can also microwave individual portions for convenience, but the oven helps maintain the crispy bacon and cheese topping.
FAQs
Can I use canned jalapeños instead of fresh ones?
Absolutely! Pickled jalapeños add a tangy nuance alongside the heat. Just be mindful of the extra moisture from canned varieties and pat them dry before adding to avoid excess liquid in the casserole.
Is this casserole suitable for meal prepping?
Yes, it’s a fantastic meal prep dish. You can fully make and bake it, then portion it into containers for easy lunches or dinners throughout the week. It reheats well and maintains its creamy texture.
Can I substitute the chicken for another protein?
Sure! While chicken breast is ideal, cooked and chopped turkey or even cooked ground meat can be great alternatives. Just adjust cooking times if starting from raw meat.
How spicy is this Keto Jalapeño Popper Casserole Recipe?
The heat level can be easily customized. Use fewer jalapeños or remove the seeds for a milder version, or add more if you love extra spice. It’s all about matching your personal preference.
What can I add to make this recipe dairy-free?
Dairy-free substitutions like vegan cream cheese, sour cream alternatives, and non-dairy shredded cheese can be used, though it will alter the texture and flavor slightly. Experiment with trusted brands that melt well for best results.
