This oven baked 3-ingredients lazy Havarti penne is the kind of weeknight recipe that earns a permanent spot in the rotation because it is simple, comforting, and surprisingly rich for so little effort. Havarti melts into a smooth, buttery sauce that clings beautifully to penne, and a quick bake gives the top those irresistible browned edges that make a basic pasta feel like a true casserole.
Serve this with a crisp green salad, simple roasted broccoli, or garlicky green beans to balance the richness. A side of toasted bread is especially nice for scooping up the creamy cheese from the corners of the dish, and if you want to round it out further, this pasta also pairs well with rotisserie chicken or a few slices of roasted tomato on the side.
Oven Baked 3-Ingredients Lazy Havarti Penne
Servings: 4 to 6
Ingredients
12 ounces penne pasta
Directions
1. Heat the oven to 375°F and lightly grease a medium baking dish or casserole dish.
2. Bring a large pot of salted water to a boil and cook the penne until just al dente, about 1 to 2 minutes less than the package directions. Drain well.
3. Return the drained penne to the pot and stir in the marinara sauce and about three quarters of the Havarti until the pasta is evenly coated.
4. Transfer the mixture to the prepared baking dish and scatter the remaining Havarti evenly over the top.
5. Bake uncovered for 20 to 25 minutes, until the cheese is fully melted and the edges are bubbling and lightly browned.
6. Let the pasta rest for 5 minutes before serving so the sauce thickens slightly and the cheese settles into the penne.
Variations & Tips
Use block Havarti if possible: A block you shred yourself usually melts more smoothly than pre-shredded cheese, which can contain anti-caking agents. If sliced Havarti is what you have, that works fine too; just tear it into smaller pieces for more even coverage.
Choose your sauce carefully: Since there are only three ingredients, the flavor of the marinara matters quite a bit. A sauce with garlic, basil, or a touch of chili can shift the whole character of the dish without adding extra work.
Add a crisp top: If you like deeper browning, place the dish under the broiler for 1 to 2 minutes at the end, watching closely. Havarti browns quickly, so this is one of those moments when it pays to stay by the oven.
Swap the pasta shape: Ziti, rigatoni, or medium shells can stand in for penne without changing the method. Shapes with ridges or hollow centers do an especially nice job of catching the melted cheese and sauce.
Make it a fuller meal: This recipe welcomes practical additions such as cooked spinach, sautéed mushrooms, shredded rotisserie chicken, or browned Italian sausage. Stir them in with the sauce so everything heats through as the pasta bakes.
