Ingredients

• 20–24 jumbo pasta shells
• 3 cups marinara sauce (homemade or your favorite jarred)
• 2 cups whole-milk ricotta cheese
• 2 cups shredded low-moisture mozzarella, divided
• 1/2 cup grated Parmesan or Pecorino Romano, divided
• 1 large egg
• 2 cups fresh baby spinach, chopped (optional but recommended)
• 2 cloves garlic, minced
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon dried Italian seasoning (or 1/2 tsp oregano + 1/2 tsp basil)
• 1/4 teaspoon crushed red pepper flakes (optional)
• 1/2 teaspoon kosher salt, plus more for pasta water
• 1/4 teaspoon black pepper
• 2 tablespoons olive oil

How to Make It – Instructions

1. Boil the shells smart: Bring a big pot of salted water to a boil. Cook shells 1–2 minutes shy of package directions (they’ll finish in the oven).

   Drain and toss with a drizzle of olive oil so they don’t stick.

2. Sauté the flavor base: In a skillet, heat olive oil over medium. Add garlic and cook 30 seconds until fragrant. Stir in chopped spinach until wilted, 1–2 minutes.

   Let cool slightly.

3. Mix the filling: In a bowl, combine ricotta, 1 1/2 cups mozzarella, 1/4 cup Parmesan, egg, sautéed spinach, parsley, Italian seasoning, red pepper flakes, salt, and black pepper. Stir until creamy and well combined.
4. Prep the pan: Spread 1 to 1 1/2 cups marinara over the bottom of a 9×13-inch baking dish.
5. Stuff the shells: Fill each shell with about 2 tablespoons of the cheese mixture. Nestle them open-side up in the sauced baking dish.
6. Sauce and top: Spoon the remaining marinara over the shells.

   Sprinkle with the remaining mozzarella and Parmesan.

7. Bake: Cover loosely with foil (tent it so cheese doesn’t stick). Bake at 375°F (190°C) for 20 minutes. Remove foil and bake 10–15 minutes more, until bubbly with golden spots.
8. Rest and serve: Let rest 5–10 minutes so everything sets.

   Garnish with extra parsley or basil if you’re feeling fancy.

How to Store

• Fridge: Cool completely, then store in an airtight container for 3–4 days. Reheat covered at 350°F until warmed through, or microwave in short bursts.
• Freezer (unbaked): Assemble in a freezer-safe dish, wrap tightly, and freeze up to 2 months. Bake from frozen at 350°F, covered, 45–60 minutes, then uncover 10–15 minutes to brown.
• Freezer (baked leftovers): Portion into freezer-safe containers.

  Reheat at 350°F until hot, or thaw overnight for faster heating.

Health Benefits

• Protein boost: Ricotta, mozzarella, and Parmesan deliver solid protein to keep you full and happy.
• Calcium and bone support: Dairy brings calcium and vitamin B12—good for bones and energy levels.
• Add greens without a lecture: Spinach sneaks in iron, folate, and vitamin K. No one complains because, cheese.
• Portion control built-in: Stuffed shells make it easy to serve measured portions (until you “accidentally” go back for two more).

Pitfalls to Watch Out For

• Overcooking the shells: They’ll tear during stuffing and turn mushy in the oven. Keep them slightly underdone.
• Watery filling: If using frozen spinach, squeeze it dry.

  Too much moisture = soupy bake.

• Skimping on sauce: Dry shells are a crime. Make sure the bottom is well sauced and the tops get a generous spoonful.
• Cheese overload on top too soon: Cover for the first bake so the cheese melts without burning. Then uncover to brown.
• Under-seasoning: Ricotta is mild.

  Salt the filling properly and use herbs for depth.

Different Ways to Make This

• Classic meat lover: Brown italian sausage or ground beef with onions. Stir into the marinara or the cheese filling for extra richness.
• Veggie garden edition: Add sautéed mushrooms, zucchini, or roasted red peppers to the filling. More texture, more flavor.
• White sauce twist: Swap marinara for a light béchamel or Alfredo.

  Top with mozzarella and a sprinkle of nutmeg for a cozy vibe.

• Pesto punch: Mix 2–3 tablespoons of pesto into the ricotta filling for herby brightness. FYI, it smells amazing.
• High-protein ricotta: Stir in cottage cheese (blended smooth) or mascarpone for extra creaminess and protein.
• Spicy arrabbiata: Use a spicy tomato sauce and boost red pepper flakes in the filling. For the heat seekers.
• Gluten-free: Use gluten-free jumbo shells and check your sauce label for hidden wheat.

FAQ

Can I make these ahead?

Yes.

Assemble up to 24 hours in advance, cover, and refrigerate. Add 5–10 extra minutes to the bake time if going straight from the fridge.

What if I can’t find jumbo shells?

Use manicotti tubes with the same filling, or layer the filling between lasagna sheets for a lazy lasagna vibe. Not identical, but still delicious.

How do I prevent the shells from sticking after boiling?

Drain well, toss with a little olive oil, and spread on a sheet pan to cool in a single layer.

Clumped shells are the enemy of clean stuffing.

Is there a lighter version?

Use part-skim ricotta and mozzarella, add extra spinach, and keep the cheese topping modest. You’ll still get cheesy satisfaction without the full send.

Which marinara should I use?

Choose a sauce you’d happily eat with a spoon. A simple, low-sugar marinara with garlic and basil is ideal.

Homemade is great; a quality jar works too, IMO.

Can I freeze individual portions?

Absolutely. Pack two or three shells with sauce into small containers. They reheat beautifully for work lunches or solo dinners.

What sides go best?

A crisp Caesar or mixed green salad and garlicky bread.

Add roasted broccoli if you want something green that fights back a little.

Why add an egg to the filling?

It binds the cheeses so the filling sets instead of oozing everywhere. Your future tidy slices will thank you.

In Conclusion

Cheesy Stuffed Shells are the rare unicorn: simple to make, crowd-pleasing, and endlessly adaptable. With just a few smart moves—al dente shells, well-seasoned filling, and plenty of sauce—you’ll get that bubbly, golden-pan moment every time.

Keep a batch in the freezer, keep a jar of good marinara on deck, and you’ve basically hacked family dinner. Now grab a fork and claim the corner piece with the crispy cheese edges—you earned it.
