- 12 ounces penne pasta: Choose penne for its ability to hold onto creamy sauces and create that perfect bite.

How to Make Baked Penne with Spinach, Ricotta & Fontina
Step 1: Prep and Cook the Pasta
First things first, get your oven cranked up to 375°F (190°C) so it’s ready for action. Boil the penne in a big pot of salted water and cook just until al dente. Think firm but tender—this prevents the pasta from getting mushy in the oven. Drain well and set it aside while you prepare the rest.
Step 2: Sauté Garlic and Spinach
Grab your largest skillet and warm the olive oil over medium heat. Toss in the minced garlic and let it sizzle for 30 seconds, just until fragrant (your kitchen will already start to smell amazing). Add in all that fresh baby spinach; it’ll look like a lot but will wilt down fast, becoming intensely green and tender in just 2 or 3 minutes. Turn off the heat and let the mixture cool slightly.
Step 3: Mix the Creamy Filling
In a big mixing bowl, combine the ricotta, grated Parmesan, egg, salt, and pepper. Give this a good stir until everything is smooth. Gently fold in the sautéed spinach and cooked penne. You’re looking for an even distribution so there’s a little bit of everything in every forkful.
Step 4: Assemble the Baked Penne with Spinach, Ricotta & Fontina
In a 9×13-inch baking dish, spread half of the marinara sauce over the bottom—this stops sticking and infuses the pasta with saucy goodness. Pile in your pasta and ricotta mixture, smoothing it out. Spoon the rest of the marinara on top, spreading it to the edges. Sprinkle the Fontina cheese in a thick, even layer over everything. Soon, you’ll have that gorgeous cheesy crust!
Step 5: Bake to Golden Perfection
Slide the dish into your preheated oven and bake for 25 to 30 minutes. You’re aiming for bubbling edges and a golden, slightly crispy cheese top. Rest the Baked Penne with Spinach, Ricotta & Fontina for a few minutes before serving—this keeps slices neat and lets the flavors settle into harmony.
How to Serve Baked Penne with Spinach, Ricotta & Fontina

Garnishes
Give your Baked Penne with Spinach, Ricotta & Fontina an Italian restaurant flourish with a sprinkle of fresh basil, flat-leaf parsley, or even extra Parmesan. A little chopped sun-dried tomato or chili flakes can add a pop of color and just the right kick.
Side Dishes
This pasta bake is already a star but loves good company! Serve with warm, crusty garlic bread to soak up every last bit of marinara. A crisp green salad tossed in lemony vinaigrette provides a refreshing counterpoint to all that creamy, melted cheese.
Creative Ways to Present
For an elevated touch, portion the Baked Penne with Spinach, Ricotta & Fontina into mini cast iron skillets or ramekins—perfect for dinner parties and everyone gets their golden corner. Or, try layering extra roasted veggies like zucchini or bell peppers between the pasta for a colorful, make-it-your-own twist.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store cooled portions in a tightly covered container in the refrigerator. Baked Penne with Spinach, Ricotta & Fontina keeps well for up to 3 days, and the flavors just keep developing.
Freezing
Want to freeze for a future easy dinner? Assemble the entire dish right up to the baking step, cover tightly with foil, and freeze. When ready to enjoy, thaw overnight in the fridge and bake as directed. It’s the ultimate meal prep magic trick!
Reheating
To reheat, spoon single servings into a microwave-safe dish, cover, and warm until hot. For larger portions, pop the whole baking dish (covered with foil) into a 350°F oven until heated through. If the top looks dry, a splash of marinara does wonders to revive things.
FAQs
Can I add meat to Baked Penne with Spinach, Ricotta & Fontina?
Absolutely! For extra heartiness, stir in cooked crumbled Italian sausage or diced grilled chicken along with the pasta and ricotta mixture. It’s a fantastic way to satisfy bigger appetites.
What’s the best substitute for Fontina cheese?
If Fontina isn’t available, mozzarella is an easy swap—choose whole milk for the best stretch factor. For a little more flavor, try Gruyère or provolone; both melt beautifully as well.
Can I use frozen spinach?
Yes, just thaw and squeeze it very well to remove excess water. Use about 10 ounces frozen spinach to substitute for the fresh and stir it right into the ricotta mixture as directed.
Is Baked Penne with Spinach, Ricotta & Fontina gluten free?
It isn’t by default, but you can easily make it gluten free by using your favorite gluten-free penne. Be sure to check your marinara sauce and cheeses as well, just in case!
Can I prep Baked Penne with Spinach, Ricotta & Fontina ahead of time?
Certainly! Assemble the casserole up to a day in advance, then cover and refrigerate. When ready to bake, add an extra few minutes to the baking time if starting from cold. It’s perfect for entertaining or busy weekdays.
