Ingredients Overview

Here’s a breakdown of what makes this dish so delicious:

Pasta Shells

• Jumbo pasta shells: Their shape is perfect for stuffing. Cook them al dente so they don’t tear while filling.

• Tip: Boil a few extras in case some break during cooking.

Cheese Filling

• Ricotta cheese: Creamy, mild, and the base of the filling.

• Mozzarella: Adds gooey meltiness inside and on top.

• Parmesan: Brings salty depth and nutty flavor.

• Egg: Helps bind the filling.

• Garlic and nutmeg: Boost the savory flavor and warmth.

Substitutions:

• Use cottage cheese for a lighter version.

• Vegan ricotta and cheese shreds work well for dairy-free alternatives.

Spinach

• Frozen spinach: Thawed and squeezed dry is easiest and most budget-friendly.

• Fresh spinach: Sauté and cool before mixing in.

Tip: Squeeze spinach thoroughly to avoid watery filling.

Sauce

• Marinara sauce: Use store-bought or homemade. A garlicky, basil-rich sauce complements the mild filling beautifully.

Options:

• Add crushed red pepper to the sauce for heat.

• Use a creamy tomato sauce or vodka sauce for richness.

Garnish

• Fresh basil or parsley: Adds freshness and a pop of color after baking.

Step-by-Step Instructions

Step 1: Cook the Shells

Boil jumbo shells in salted water until just shy of al dente (usually 1–2 minutes less than package directions). Drain and cool on a baking sheet to prevent sticking.

Step 2: Make the Ricotta Filling

In a large bowl, combine:

• 15 oz ricotta cheese

• 1 egg

• 1 1/2 cups shredded mozzarella

• 1/2 cup grated Parmesan

• 1 clove garlic, minced

• 1/4 tsp ground nutmeg

• Salt and pepper to taste

• 10 oz frozen spinach (thawed and squeezed dry)

Mix until creamy and fully combined.

Step 3: Fill the Shells

Spoon the cheese mixture into each shell using a small spoon or piping bag. Each shell should be generously filled but not overflowing.

Step 4: Assemble the Dish

• Spread 1 cup of marinara sauce in the bottom of a 9×13 baking dish.

• Arrange filled shells in a single layer over the sauce.

• Spoon remaining marinara over the top and sprinkle with extra mozzarella and Parmesan.

Step 5: Bake

Cover the dish with foil and bake at 375°F (190°C) for 25 minutes.

Remove foil and bake uncovered for an additional 10–15 minutes, until bubbly and golden on top.

Let rest for 5–10 minutes before serving.

Tips, Variations & Substitutions

Tips

• Don’t overcook the shells—they’ll finish cooking in the oven.

• Use a piping bag (or zip bag with a corner cut) for easier, cleaner filling.

• For extra flavor, stir fresh chopped basil or parsley into the filling.

Variations

• Meaty: Add cooked crumbled sausage or ground beef to the sauce layer.

• Spicy: Mix chili flakes or Calabrian chili paste into the cheese or sauce.

• Cheesy Upgrade: Swap in fontina, provolone, or smoked mozzarella for deeper flavor.

• White Sauce Version: Use béchamel or Alfredo sauce instead of marinara.

Dietary Swaps

• Gluten-Free: Use GF jumbo shells.

• Vegan: Use dairy-free ricotta (almond or tofu-based), egg substitute, and vegan cheese.

• Low-Carb: Swap pasta for thinly sliced zucchini “shells” rolled around the filling.
