Keto Jalapeño Popper Casserole
Back when I first started leaning into low-carb meals, I thought comfort food would have to take a backseat. No creamy pasta, no buttery potatoes… just sad piles of lettuce and grilled chicken. But let me tell you, this Keto Jalapeño Popper Casserole saved me from the brink of diet despair. It’s cheesy, rich, spicy, and it hits all the right notes — without the carbs.
The first time I made this, my partner walked into the kitchen, sniffed the air, and said, “Whatever that is, we’re making it again tomorrow.” And we did. Then again the next week. And now it’s a staple in our dinner rotation, whether we’re in keto mode or not.
This casserole tastes indulgent, but it’s surprisingly easy to throw together. If you’re craving something bold, creamy, and satisfying — but still keeping it keto — this is your go-to.

Ingredients List
Main Ingredients
- 2 cups cooked chicken breast – shredded
- 6 slices bacon – cooked and crumbled
- 5 medium jalapeños – seeds removed, sliced
- 8 oz cream cheese – softened
- ½ cup sour cream
- 1 ½ cups shredded cheddar cheese
- ½ cup shredded mozzarella cheese
Seasoning
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and black pepper – to taste
Topping (optional)
- Extra jalapeño slices
- Crumbled bacon
- Fresh chives or parsley for garnish
Directions
Step 1: Preheat and prep
Set your oven to 375°F (190°C). Grease an 8×8-inch baking dish and set aside. Cook and crumble the bacon if you haven’t already.
Step 2: Make the creamy base
In a large bowl, mix the cream cheese, sour cream, garlic powder, onion powder, and a pinch of salt and pepper until smooth. Stir in shredded chicken, half of the bacon, and half of the cheddar.
Step 3: Layer it up
Spread the mixture into the baking dish. Top with sliced jalapeños, the remaining cheddar and mozzarella, and the rest of the bacon.
Step 4: Bake to bubbly
Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbling. For a golden top, broil for an extra 2 minutes at the end — just keep an eye on it!
Step 5: Garnish and serve
Let it cool for 5–10 minutes, then garnish with fresh herbs or extra jalapeño slices if desired. Serve warm.
Cooking Notes & Common Mistakes
Make sure the cream cheese is fully softened before mixing — otherwise, it won’t blend smoothly.
Adjust the number of jalapeños to suit your heat level. Removing all seeds keeps it mild.
Use rotisserie chicken for an even quicker prep.
If you like texture, toss in chopped green onions or diced bell pepper.
Serving Suggestions & Pairings
Serve with a side of leafy greens tossed in olive oil and lemon juice.
It’s great on its own, but also perfect with cauliflower rice or roasted zucchini.
Add a dollop of guacamole or a side of sour cream to mellow out the heat.
For brunch, serve it alongside scrambled eggs — it’s a hit.
Variations and Customizations
Swap chicken for ground turkey or beef if that’s what you have.
Add cooked mushrooms or spinach for more veggie power.
Use pepper jack cheese for a spicier twist.
Mix in diced tomatoes (drained well) for a pop of color and moisture.
Make it dairy-free using plant-based cream cheese and cheese alternatives.
Storage & Reheating
Store leftovers in a sealed container in the fridge for up to 4 days.
To reheat, pop a slice in the microwave for 1–2 minutes or bake at 325°F until warmed through.
It freezes well too — wrap portions tightly and freeze for up to 2 months. Thaw overnight before reheating.

Frequently Asked Questions (FAQs)
1. Can I make this ahead of time?
Yes! Assemble it a day in advance, store in the fridge, and bake when ready to serve.
2. Is this dish spicy?
It has a mild to medium kick. Remove all jalapeño seeds for less heat, or leave some in for more.
3. Can I use canned jalapeños?
Yes, but drain them well to avoid extra moisture in the casserole.
4. What’s the best chicken to use?
Leftover roasted or rotisserie chicken works great. Just shred it finely.
5. Can I make this in a larger pan?
Definitely — double the ingredients and use a 9×13-inch baking dish. Bake a few minutes longer if needed.
