Ingredients
One of the joys of Stuffed Shells Florentine is its reliance on simple, high-quality ingredients that harmonize into a decadent whole. Below is the classic ingredient list, with suggested brands and variants where helpful:
| Ingredient | Quantity | Notes |
|---|---|---|
| Jumbo pasta shells | 12 oz package | Barilla or other brands |
| Ricotta cheese | 30 oz (two 15-oz containers) | Whole or part-skim |
| Frozen chopped spinach | 10 oz package | Thawed, squeezed dry |
| Parmesan cheese | 16 oz (two 8-oz bags), shredded | Shredded or freshly grated |
| Egg | 1 large | Beaten |
| Salt | 1/2 teaspoon | Fine or kosher |
| Black pepper | 1/4 teaspoon | Freshly ground preferred |
| Dried oregano | 1 teaspoon | |
| Dried basil | 1 teaspoon | |
| Spaghetti sauce | 45 oz jar | Or favorite homemade sauce |
Optional Additions
- Mozzarella cheese (for topping—adds extra melt and richness)
- Grated Romano cheese (can substitute for some Parmesan)
- Fresh parsley or basil (for garnish)
Step-by-Step Instructions
Prep the Pasta Shells:
- Bring a large pot of salted water to a boil. Add the jumbo shells and cook according to package directions—usually around 12 minutes, but pull them off the heat while still al dente to prevent splitting during stuffing and baking.
- Drain the shells using a colander. Quickly rinse under cold water to stop the cooking process and set aside on waxed paper or a cutting board to cool.
Prepare the Filling:
- In a large mixing bowl, combine ricotta cheese, spinach (thawed and squeezed dry to remove excess liquid), one beaten egg, half the parmesan, salt, black pepper, oregano, and basil.
- Mix thoroughly until the filling is well-blended and creamy.
Fill the Shells:
- Using a spoon, gently stuff each cooled shell with the ricotta-spinach filling—being careful not to split the pasta.
Assemble the Casserole:
- Lightly coat the bottom of a 10×15-inch baking dish with a thin layer of spaghetti sauce.
- Arrange the filled shells in the dish. If necessary, layer some shells to fit them all, as even modest crowding bakes up beautifully.
- Pour the remaining sauce evenly over the shells.
- Top with the rest of the parmesan cheese (and mozzarella, if using), covering the surfaces for bubbly, golden cheese pull.
Bake:
- Cover the dish with aluminum foil to lock in moisture.
- Bake at 350°F (175°C) for 30–40 minutes, or until the casserole is heated through and cheese is fully melted.
- Uncover for the last 5–10 minutes of baking for a slightly golden top, if desired.
Serve:
- Let the casserole rest for 5–10 minutes before serving so it firms up and slices easily.
- Garnish with fresh parsley or basil if available and enjoy hot.
Tips & Tricks for Success
- Al dente pasta is essential—slightly undercook the shells so they survive stuffing and finish evenly in the oven.
- Drain spinach thoroughly. Squeeze out as much liquid as possible with your hands and paper towels. Excess water in the filling can lead to soggy shells.
- Make ahead: The casserole can be assembled a day in advance, covered, and refrigerated. Let stand at room temperature while the oven preheats; add 10–15 minutes to the baking time if straight from the fridge.
- Use quality cheese. Freshly shredded Parmesan and ricotta provide superior flavor and melt compared to pre-grated options.
- Layering: Overlapping shells is fine—just make sure sauce and cheese cover all surfaces, so everything bakes evenly.
- Freezer friendly: Assemble and freeze unbaked; thaw in fridge overnight before baking. Great for meal prep or gifting.
Recipe Variations
- Cheese Variations: Mix in grated mozzarella or Romano cheese to the filling for a different flavor profile.
- Meaty Shells: Add cooked Italian sausage, ground beef, or chicken to the filling for heartier shells.
- Seafood Option: Fold in chopped cooked shrimp or crab for a seafood Florentine twist.
- Vegan Adaptation: Substitute with dairy-free cheeses and flax egg as needed; use vegan marinara.
- Gluten-Free: Use gluten-free pasta shells and double-check sauce ingredients.
- Saucy Switch-up: Try Alfredo or a pink sauce instead of tomato sauce for a different take.
Serving Suggestions
Stuffed Shells Florentine is hearty on its own, but sides can make it a complete meal:
- Garlic bread or crusty French bread for soaking up sauce
- Green salad with Italian vinaigrette or balsamic reduction
- Roasted or steamed vegetables (e.g., broccoli, asparagus, carrots)
- Antipasto platter with olives, artichoke hearts, and Italian cured meats (optional for non-vegetarian gatherings)
