Potluck season is here, and whether you’re heading to a office gathering, family reunion, or neighborhood block party, you need a recipe that’s easy to transport, simple to prepare, and absolutely delicious. This classic Baked Pasta with Spinach and Ricotta is the ultimate potluck MVP—it’s hearty, feeds a crowd, and tastes even better the next day.
I’ve been making this dish for years, and it never fails to earn compliments and empty plates. The beauty of this recipe is that it comes together in about 30 minutes of active prep time, then bakes while you finish getting ready. You can assemble it at home, transport it in the same dish you’ll bake it in, and simply pop it in the oven at your destination. No special equipment needed, no complicated techniques—just honest, comforting Italian-American food that everyone loves.
The combination of creamy ricotta, earthy spinach, and tender pasta creates layers of flavor and texture that make this dish feel fancy enough for a special occasion, yet casual enough for a weeknight dinner. I love adding fresh basil and a touch of nutmeg to elevate the flavors beyond basic pasta bake. This recipe also works beautifully alongside Easy Garlic Bread and a simple Fresh Garden Salad.

Ingredients
- 1 pound penne pasta
- 2 tablespoons olive oil
- 1 medium yellow onion, finely diced
- 4 cloves garlic, minced
- 10 ounces fresh spinach (or 5 ounces frozen, thawed)
- 15 ounces ricotta cheese, room temperature
- 8 ounces mozzarella cheese, shredded
- ½ cup grated Parmesan cheese
- 1 large egg
- ¼ teaspoon freshly grated nutmeg
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ cup fresh basil, chopped (plus more for garnish)
- 24 ounces marinara sauce (store-bought is fine)
- ½ cup reserved pasta water
- Cooking spray or butter for greasing the baking dish
Instructions
- Preheat your oven to 375°F. Grease a 9×13-inch baking dish with cooking spray or butter and set aside.
- Fill a large pot with salted water and bring to a rolling boil. Add penne pasta and cook according to package directions until just al dente (usually 2 minutes less than package time since it will continue cooking in the oven). Reserve ½ cup of pasta water before draining. Drain the pasta and set aside.
- In a large skillet, heat olive oil over medium heat. Add diced onion and sauté for 3-4 minutes, stirring occasionally, until the onion becomes translucent and fragrant.
- Add minced garlic to the skillet and cook for 1 minute more, stirring constantly, until the raw garlic smell fades and the mixture becomes aromatic.
- Add fresh spinach to the skillet in batches, stirring and allowing each batch to wilt before adding more. This should take about 3-4 minutes total. If using frozen spinach, simply add it and stir until completely warmed through. Once wilted, remove from heat and let cool for 2 minutes.
- In a large mixing bowl, combine ricotta cheese, half of the shredded mozzarella (about 4 ounces), Parmesan cheese, and egg. Stir until well combined.
- Add the cooled spinach mixture to the ricotta mixture and fold gently to combine. Season with nutmeg, salt, pepper, and fresh basil. Fold until everything is evenly distributed—do not overmix.
- Add the cooked pasta to the ricotta-spinach mixture and fold gently until every noodle is coated with the creamy mixture.
- Pour the marinara sauce into the prepared baking dish, spreading it evenly across the bottom. This prevents the pasta from sticking and creates a saucy base.
- Transfer the pasta mixture to the baking dish, spreading it evenly with a spatula. If the mixture seems dry, add reserved pasta water, a few tablespoons at a time, until it reaches your desired consistency.
- Sprinkle the remaining shredded mozzarella cheese evenly over the top of the pasta bake.
- Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-12 minutes, until the cheese on top is melted, bubbly, and starting to turn golden brown.
- Remove from the oven and let rest for 5 minutes before serving. Garnish with fresh basil and additional Parmesan cheese if desired.
- To transport: Cover cooled baked pasta with plastic wrap and foil, then place in an insulated container with towels. Reheat at destination at 350°F, covered, for 15-20 minutes until heated through.
Pro Tips
- Make-Ahead Magic: This dish can be assembled up to 24 hours in advance. Simply prepare through step 11, cover tightly with plastic wrap and foil, and refrigerate. When ready to bake, add 5-10 minutes to the cooking time since it will be cold.
- Freezer-Friendly: You can freeze the assembled (but unbaked) pasta bake for up to 3 months. Wrap tightly in plastic wrap and foil. Bake from frozen at 350°F for 50-60 minutes, covered with foil for the first 40 minutes.
- Cheese Variations: While ricotta is traditional, you can substitute with a combination of mascarpone and cottage cheese for a slightly different texture. For a richer dish, add 2 tablespoons of cream cheese to the ricotta mixture.
- Vegetable Additions: Feel free to add sautéed mushrooms, roasted red peppers, or sun-dried tomatoes to the filling. Add them in step 8 along with the spinach mixture.
- Sauce Selection: While marinara is classic, you can use Alfredo sauce for a creamier version, or a combination of both for a pink sauce variation.
- Pasta Alternatives: This recipe works beautifully with rigatoni, ziti, or even lasagna noodles cut into smaller pieces. Avoid very small pasta like orzo or ditalini as they can get lost in the sauce.
- Storage: Leftovers keep in the refrigerator for up to 4 days in an airtight container. Reheat gently in a 325°F oven, covered with foil, until warmed through.
- Serving Suggestions: Pair with garlic bread, a crisp green salad, and your favorite red wine. A simple arugula salad with lemon vinaigrette complements the richness beautifully.
- For Picky Eaters: If you’re serving at a potluck with spinach skeptics, finely chop the spinach so it blends seamlessly into the filling—the flavors remain but it’s less visually obvious.
- Scaling Up: This recipe doubles easily. Use a 9×13-inch baking dish and increase baking time by 10-15 minutes, or use two baking dishes and keep one for later.
