This oven baked 5-ingredient jalapeño popper pasta is exactly the kind of dish I bring to neighborhood parties when I don’t have the time (or energy) for anything fussy. It has all the flavors of classic jalapeño poppers—creamy, cheesy, a little spicy, and plenty of crispy bacon—tucked into a big pan of cozy pasta. I made this for my neighbor’s retirement party, slid it onto the buffet next to a dozen other casseroles, and came home with an empty dish and three texts asking for the recipe. It’s simple, crowd-pleasing, and perfect for busy weeknights or potlucks when you want something that looks and tastes like you put in way more effort than you actually did.
This pasta is rich and cheesy, so I like to pair it with something fresh and crunchy—think a simple green salad with a tangy vinaigrette or a bowl of sliced cucumbers and cherry tomatoes. Garlic bread or warm dinner rolls are great for scooping up the extra creamy sauce. If you’re serving this at a party, round out the table with a veggie tray and ranch dip, a big bowl of tortilla chips with salsa, and maybe a light fruit salad for something sweet and refreshing alongside the spicy, smoky flavors.
Oven Baked 5-Ingredient Jalapeño Popper PastaServings: 8
Ingredients
12 oz dry penne pasta
8 oz cream cheese, softened and cubed
2 cups shredded sharp cheddar cheese, divided
6 slices thick-cut bacon, cooked crispy and crumbled (reserve 1 tablespoon bacon drippings if possible)
4 fresh jalapeños, seeded and finely chopped (leave some seeds for extra heat, optional)
1 teaspoon kosher salt
1/2 teaspoon black pepper
1/2 cup reserved hot pasta water (as needed for thinning sauce, optional but recommended)
Nonstick cooking spray or a little oil, for greasing the baking dish
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass baking dish with nonstick cooking spray or a little oil so the pasta doesn’t stick.
Bring a large pot of salted water to a boil. Add the penne and cook until just al dente, 1–2 minutes less than the package directions so it doesn’t get mushy in the oven. Before draining, scoop out about 1/2 cup of the hot pasta water and set it aside. Drain the pasta well.
While the pasta cooks, cook the bacon in a skillet over medium heat until very crispy. Transfer the bacon to a paper towel–lined plate to cool, then crumble it into small pieces. Carefully reserve about 1 tablespoon of the bacon drippings in the skillet if you can.
Add the chopped jalapeños to the skillet with the bacon drippings (or a teaspoon of oil if you don’t have drippings). Sauté over medium heat for 2–3 minutes, just until slightly softened and fragrant. This takes a bit of the raw bite out but keeps some crunch. Remove from heat.
In the still-warm pasta pot (off the heat), add the cream cheese cubes, 1 1/2 cups of the shredded cheddar, salt, pepper, and a splash (2–3 tablespoons) of the reserved hot pasta water. Stir until the cheeses start to melt into a thick, creamy sauce, adding more pasta water a tablespoon at a time as needed to get a smooth, coat-the-pasta consistency.
Add the drained penne, sautéed jalapeños, and most of the crumbled bacon to the pot, reserving a small handful of bacon for topping. Stir everything together until the pasta is evenly coated and the jalapeños and bacon are well distributed.
Pour the mixture into the prepared glass baking dish and spread it into an even layer. Sprinkle the remaining 1/2 cup shredded cheddar and the reserved crumbled bacon evenly over the top for that crispy, cheesy crust.
Bake uncovered at 375°F (190°C) for 18–22 minutes, or until the cheese on top is melted, bubbly around the edges, and just starting to turn golden brown. The pasta should be hot all the way through.
Let the dish rest for about 5–10 minutes before serving so the sauce can thicken slightly and the scoops hold together. Serve straight from the glass baking dish with a big spoon—expect the cheese to stretch and the bacon and jalapeño pieces to show in every scoop. If you’re taking this to a party, cover it loosely with foil for transport and rewarm in a low oven if needed.
Variations & Tips
To keep this truly 5-ingredient, think of the main five as penne, cream cheese, cheddar, bacon, and jalapeños—everything else is optional support. If you like things spicier, leave some of the jalapeño seeds in or add a pinch of red pepper flakes to the cheese sauce. For a milder version, use fewer jalapeños or swap one or two for a milder pepper like poblano. You can also mix in a can of drained diced green chiles if you want more flavor without extra heat. For a slightly lighter dish, you can use reduced-fat cream cheese and turkey bacon; just know the sauce may be a bit less rich, so don’t skip the reserved pasta water to keep it creamy. If you’re cooking ahead, assemble the pasta through the point of adding it to the baking dish, cover tightly, and refrigerate up to 24 hours; when ready to bake, let it sit at room temp for 20–30 minutes and add 5–10 extra minutes of bake time until hot and bubbly. Leftovers keep well in the fridge for up to 3–4 days; reheat covered in the oven or in the microwave with a splash of milk or water to loosen the sauce. Food safety tips: Cook bacon until fully crisp and no visible raw fat remains, and cool it on paper towels to remove excess grease. Handle jalapeños carefully—avoid rubbing your eyes, and wash your hands and cutting board well after chopping. Refrigerate any leftovers within 2 hours of baking, and reheat to at least 165°F (74°C) before serving again.
