This oven baked 4-ingredient Philly cheesesteak pasta is exactly the kind of weeknight comfort food my husband asks for on repeat. The first time I tested it, he went back for seconds, packed it for lunch the next day, and then casually requested it again “sometime this week”… which turned into three times in one week. It has all the flavors of a classic Philly cheesesteak—tender beef, sweet caramelized onions, and melty provolone—tucked into cozy curls of pasta and baked until bubbly. It’s a true busy-night hero recipe: one pan, minimal chopping, and the kind of cheesy, beefy goodness that makes everyone at the table happy with hardly any effort.
This pasta is rich and cheesy, so I like to balance it with something fresh and crisp—think a simple green salad with a tangy vinaigrette or sliced cucumbers and cherry tomatoes tossed with a little olive oil and salt. Garlic bread or a warm baguette is great for scooping up the extra cheesy sauce from the bottom of the casserole dish. For drinks, a cold beer, sparkling water with lemon, or a light red wine pairs nicely with the savory beef and provolone. If you want to stretch the meal for a crowd, serve it alongside roasted broccoli or green beans so you’ve got a veggie on the plate without adding much work.
Oven Baked 4-Ingredient Philly Cheesesteak Pasta
Servings: 6
Ingredients
12 oz cavatappi pasta (or other short, curly pasta)
1 lb thinly sliced beef steak (such as shaved sirloin or chip steak)
2 large yellow onions, thinly sliced
12 oz sliced provolone cheese
Directions
Preheat your oven to 375°F (190°C). Lightly grease a deep 9x13-inch ceramic casserole dish and set aside.
Bring a large pot of salted water to a boil. Add the cavatappi pasta and cook until just shy of al dente, 1–2 minutes less than the package directions. The pasta will finish cooking in the oven. Drain well and set aside.
While the pasta cooks, heat a large skillet over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until very soft and deeply golden brown around the edges, 12–15 minutes. If the pan looks too dry or the onions start to scorch, add a tablespoon of water at a time to deglaze and keep them moving.
Once the onions are caramelized to your liking, push them to one side of the skillet and add the thinly sliced beef steak to the empty side. Increase the heat slightly to medium-high. Cook, stirring and breaking apart the pieces, just until the beef is no longer pink, 3–5 minutes. Turn off the heat. (If there is a lot of liquid, you can spoon off a bit so the pasta doesn’t get watery.)
Add the drained cavatappi pasta directly into the skillet with the beef and onions. Toss everything together so the pasta is evenly coated with the flavorful beefy-onion mixture.
Layer about one-third of the provolone slices over the bottom of the prepared casserole dish, slightly overlapping them to cover the surface. Spoon half of the pasta-beef-onion mixture on top of the cheese and spread into an even layer.
Add another one-third of the provolone slices over the pasta layer, then top with the remaining pasta mixture, spreading it evenly. Finish with the last one-third of the provolone slices arranged over the top, covering as much of the surface as possible for a cheesy blanket.
Cover the casserole dish tightly with foil and bake in the preheated oven for 15 minutes to heat everything through and let the cheese melt into the pasta.
Remove the foil and continue baking for another 10–15 minutes, or until the cheese on top is fully melted, bubbly around the edges, and just starting to get golden spots.
Let the casserole rest for about 5 minutes before serving so it can set slightly and the cheese thickens up. Use a large serving spoon to scoop out generous portions, making sure to get the caramelized onions and beef from the bottom of the dish along with those cheesy curls of cavatappi.
Variations & Tips
If you have a few extra minutes or ingredients on hand, you can easily dress this up while still keeping it weeknight-friendly. For a more classic Philly vibe, add thinly sliced green bell pepper to the skillet with the onions for the last 5–7 minutes of cooking. If your family likes a little heat, sprinkle red pepper flakes over the pasta before adding the final cheese layer. You can also swap half of the provolone for mozzarella for extra stretch, or use smoked provolone for a deeper, almost grilled flavor. For a slightly lighter take, use whole-wheat pasta and lean sirloin, and add a handful of baby spinach to the hot pasta before baking so it wilts right in. To make ahead, assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours; add 5–10 minutes to the covered bake time if going into the oven cold. Leftovers reheat well in the microwave with a splash of water to loosen the cheese. Food safety tips: Always cook the beef until it is no longer pink and reaches a safe internal temperature (at least 145°F/63°C for steak, checking the thickest pieces). Cool leftovers and refrigerate within 2 hours, and use them within 3–4 days. Reheat until steaming hot throughout before serving again. If you’re using pre-shaved beef from the store, keep it refrigerated and cook it the same day you open the package for best quality and safety.
