This oven baked 4-ingredients creamy fontina rigatoni is one of those hand-me-down treasures that makes you shake your head and wonder why cooking ever got so complicated. My sister passed this along to me years ago, scribbled on the back of an envelope, and she swore it "practically cooks itself." She was right. It’s pure Midwestern comfort: sturdy rigatoni, a blanket of rich cream, plenty of mild, melty fontina, and just a pinch of salt to wake everything up. It bakes in a simple foil pan until the pasta is tender and the cheese turns into a gooey, golden coat around every tube. It’s the kind of no-fuss, pantry-friendly casserole that fits right in at a church potluck, a busy weeknight, or a quiet Sunday supper when you want something warm and familiar without a lot of fuss.
Serve this creamy fontina rigatoni straight from the foil pan while it’s still bubbling and stretchy with cheese. It pairs nicely with a crisp green salad dressed in something tangy to cut through the richness, or with simple steamed green beans tossed in a little butter. Warm garlic bread or a crusty loaf is perfect for swiping through the extra sauce along the edges of the pan. For a heartier spread, set it beside roasted vegetables or a simple pan-fried pork chop, but honestly, this dish can stand on its own with just a glass of iced tea or a small bowl of fruit on the side.
Oven Baked 4-Ingredients Creamy Fontina RigatoniServings: 6
Ingredients
12 ounces dry rigatoni pasta
3 cups shredded fontina cheese (about 12 ounces)
3 cups heavy cream
1 teaspoon kosher salt
Directions
Preheat your oven to 375°F (190°C). Set a rack in the middle of the oven. Place a rectangular disposable aluminum foil baking pan (about 9x13 inches) on a sturdy sheet pan for easier handling.
Add the dry rigatoni directly into the foil pan in an even layer. There is no need to boil the pasta first; it will cook in the cream as it bakes.
Sprinkle the kosher salt evenly over the dry rigatoni, gently tossing the pasta with clean hands or a spoon so the salt is distributed throughout.
Scatter about half of the shredded fontina cheese over the dry pasta, letting some of it fall down between the tubes of rigatoni so it melts throughout the dish, not just on top.
Pour the heavy cream slowly and evenly over the rigatoni, making sure to wet as much of the pasta as possible. Gently shake the pan or nudge the pasta with a spoon so the cream settles in between the pieces of rigatoni.
Top the pan with the remaining shredded fontina, spreading it all the way to the corners so the surface is covered. This will give you that gooey, golden blanket of cheese on top.
Cover the foil pan tightly with aluminum foil, crimping the edges well so the steam stays inside. Place the pan (on the sheet pan) into the preheated oven.
Bake, covered, for 35 to 40 minutes, until the cream is hot and the pasta is starting to soften. Carefully remove the foil cover, watching for hot steam.
Stir the pasta gently from the corners toward the center, pulling some of the melted cheese and cream down into the rigatoni so everything cooks evenly. Smooth the top back out.
Return the pan to the oven, uncovered, and bake for another 15 to 20 minutes, or until the rigatoni is tender when pierced with a fork and the top is bubbling and lightly golden in spots.
If you like an extra bit of browning, you can leave the pan in the oven for an additional 3 to 5 minutes, watching closely so the cheese doesn’t burn.
Remove the pan from the oven and let the pasta rest for about 5 to 10 minutes. This short rest helps the sauce thicken slightly and cling to each tube of rigatoni.
Serve the creamy fontina rigatoni straight from the foil pan, scooping down through the top so you catch the gooey cheese, thick pasta tubes, and rich cream sauce in every portion.
Variations & Tips
For a slightly lighter version, you can replace up to 1 cup of the heavy cream with whole milk, though the sauce will be a bit less rich and thick. If you prefer a saltier bite, add an extra pinch of salt or finish each serving with a light sprinkle of flaky salt at the table. To introduce a little color and flavor without adding more ingredients, you can let the top brown a bit more in the oven for a deeper, toasty cheese flavor. If you want to stretch the dish for a crowd, serve smaller portions alongside a big salad and bread.
Food safety and handling tips: Keep the heavy cream refrigerated until you are ready to assemble the dish, and do not leave it out at room temperature for long. Use clean utensils and a clean foil pan when handling the uncooked pasta and dairy. Bake the casserole until it is piping hot and the cream is bubbling throughout; the center should be at least 165°F (74°C) if you check with a food thermometer. Refrigerate leftovers within 2 hours of baking, covered tightly in the same foil pan or transferred to a lidded container. Reheat leftovers thoroughly in the oven at 325°F (165°C) or in the microwave until steaming hot, and use within 3 to 4 days. Because this dish relies heavily on dairy, do not leave it out on the counter for extended periods after serving.
