Ingredients Overview

Jumbo Pasta Shells

• 20–24 jumbo pasta shells (you’ll cook a few extra in case of tearing)
  • Look for durum wheat shells that hold shape well during boiling and baking.
  • Gluten-free shells are a great option if needed.

Ricotta Cheese

• 15 oz whole milk ricotta
  • Creamy and mild, perfect for stuffing.
  • Can be replaced with part-skim for a lighter version or vegan ricotta for dairy-free.

Spinach

• 5 oz fresh baby spinach or 10 oz frozen spinach (thawed and drained)
  • Sautéed lightly to reduce moisture and boost flavor.
  • Kale or Swiss chard can be used for variation.

Cheese Blend

• ½ cup grated Parmesan cheese
  • Adds saltiness and nuttiness to the filling.
• 1 cup shredded mozzarella cheese
  • Melts beautifully over the top for a golden crust.

Aromatics & Seasoning

• 2 garlic cloves, minced
• 1 egg (binds the filling — can be skipped or substituted with a flax egg)
• Salt & black pepper to taste
• ¼ tsp nutmeg (optional but enhances the ricotta’s flavor)
• 1 tbsp fresh basil or parsley, chopped

Tomato Sauce

• 2½ to 3 cups marinara sauce
  • Use homemade or a high-quality store-bought sauce.
  • Roasted garlic, arrabbiata, or tomato basil varieties work well.

Step-by-Step Instructions

1. Cook the Shells

• Bring a large pot of salted water to a boil.
• Add pasta shells and cook 2 minutes less than package instructions (they’ll finish cooking in the oven).
• Drain and rinse with cold water. Place on a tray to avoid sticking.

2. Prepare the Spinach Filling

• In a skillet, sauté garlic in a little olive oil until fragrant.
• Add fresh spinach and cook until wilted (2–3 minutes). If using frozen spinach, just heat through and remove excess moisture by pressing in a towel or sieve.
• In a bowl, mix:
  • Ricotta
  • Parmesan
  • Cooked spinach
  • Egg
  • Nutmeg
  • Salt & pepper
  • Fresh herbs

3. Assemble the Shells

• Preheat oven to 375°F (190°C).
• Spread 1 cup marinara sauce across the bottom of a 9×13-inch baking dish.
• Fill each shell with about 1½ tablespoons of the ricotta-spinach mixture and place into the sauce-lined dish.

4. Top and Bake

• Spoon remaining marinara sauce over the stuffed shells.
• Sprinkle mozzarella cheese on top.
• Cover with foil and bake for 25 minutes.
• Remove foil and bake another 10 minutes until bubbly and golden.

5. Rest and Serve

• Let sit for 5–10 minutes before serving — this helps the filling set.
• Garnish with extra chopped parsley or basil.

Tips, Variations & Substitutions

• Make it spicy: Add crushed red pepper flakes to the sauce.
• Vegan version: Use dairy-free ricotta (almond or tofu-based), egg replacer, and vegan mozzarella.
• Add mushrooms: Sauté with the spinach for extra umami.
• Boost protein: Mix in cottage cheese or chopped white beans with the ricotta.
• No jumbo shells? Use cooked manicotti or layer the filling in lasagna noodles and roll them.

Storage Tip:
This dish keeps well refrigerated for up to 4 days or frozen for 2 months. Assemble ahead and freeze unbaked; bake directly from frozen, adding 15 extra minutes covered.
