This oven baked 4-ingredient bacon and pea pasta is the kind of back-pocket recipe my sister leans on when her picky kids are circling the kitchen and dinner needs to be both familiar and fun. It’s built on simple pantry and fridge staples—short pasta, frozen peas, bacon, and a good-quality jarred Alfredo sauce—so there’s nothing fussy or intimidating here. Everything bakes together in one dish into a creamy, cozy casserole with crisp bacon on top and sweet pops of peas tucked into the spirals of pasta. It borrows the spirit of classic Midwestern casseroles—hearty, kid-friendly, and comforting—while staying streamlined enough for a busy weeknight.
Serve this bacon and pea pasta straight from the baking dish with a simple green salad dressed in a tangy vinaigrette to balance the richness. Warm garlic bread or a crusty baguette is perfect for scooping up any extra creamy sauce. For adults, a chilled glass of Pinot Grigio or a light, crisp beer pairs nicely; for kids, offer sliced fresh fruit or applesauce on the side for a bit of sweetness and contrast.
Oven-Baked 4-Ingredient Bacon and Pea PastaServings: 4
Ingredients
12 oz dry rotini pasta (or other short pasta)
8 oz bacon, cut into small pieces
1 1/2 cups frozen green peas (no need to thaw)
24 oz jar Alfredo sauce (or two 12 oz jars)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass baking dish so the pasta doesn’t stick.
Bring a large pot of well-salted water to a boil. Add the rotini pasta and cook for about 2 minutes less than the package directions for al dente (the pasta will finish cooking in the oven). Drain the pasta well.
While the pasta cooks, place the bacon pieces in a large skillet over medium heat. Cook, stirring occasionally, until the bacon is browned and crisp and the fat has rendered, 7–10 minutes. Use a slotted spoon to transfer the crispy bacon to a paper towel–lined plate. Reserve 1–2 tablespoons of the bacon drippings in the skillet and discard the rest.
Pour the Alfredo sauce into the warm skillet with the reserved bacon drippings and stir over low heat just until the sauce is loosened and slightly warmed. This helps it coat the pasta more evenly. If you prefer, you can skip warming the sauce and pour it straight from the jar in the next step.
In the prepared glass baking dish, combine the drained rotini, frozen peas, and about three-quarters of the crispy bacon. Pour the Alfredo sauce evenly over the top.
Use a large spoon to gently toss everything together right in the baking dish until the pasta, peas, and bacon are well coated and the sauce is distributed. Smooth the top into an even layer, then sprinkle the remaining bacon over the surface for extra crisp bits.
Cover the baking dish tightly with foil and bake for 15 minutes. Remove the foil and continue baking for another 10–15 minutes, or until the pasta is tender, the sauce is bubbling around the edges, and the top has a few golden spots.
Let the pasta rest for 5 minutes before serving so the sauce can thicken slightly and cling to the rotini. Serve warm straight from the baking dish, making sure each portion gets plenty of peas and crispy bacon on top.
Variations & Tips
For a slightly lighter version, you can use turkey bacon and a lighter Alfredo sauce; just note that turkey bacon will render less fat, so you may want to add a teaspoon of olive oil when warming the sauce. If your kids are wary of visible peas, try using petite peas, which are smaller and sweeter, and stir them in a bit more thoroughly so they tuck into the pasta spirals. To make this ahead, assemble the dish up to the point of baking, cover tightly, and refrigerate for up to 24 hours; add 5–10 extra minutes to the covered baking time if starting from cold. If the casserole looks a bit thick after baking, stir in a splash of milk or a spoonful of hot water to loosen the sauce. You can also swap rotini for any short, ridged pasta like fusilli or cavatappi, which hold onto the creamy sauce and bacon bits especially well. For adults who like a touch of heat, offer crushed red pepper flakes at the table so everyone can season their own portion without making the whole dish spicy for kids.
