Ingredients

These French onion stuffed shells are an absolute dream! Cozy, cheesy, savory and tasting just like a bowl of french onion soup!

For the Filling

• 4 sweet onions, (thinly sliced)
• 4 tablespoons unsalted butter
• kosher salt and pepper
• ½ teaspoon dried thyme
• 2 garlic cloves, (minced)
• 8 ounces jumbo pasta shells, (you need about 20 shells)
• 2 cups ricotta cheese
• 1 large egg
• 1 cup grated gruyere cheese
• ¼ cup grated parmesan cheese, (plus more for topping)

For the Sauce

• 1 tablespoon flour
• 1 ½ cups chicken, (beef or vegetable stock)
• ⅓ cup cream

For Topping

• 1 cup grated mozzarella cheese, (for topping)
• ¼ cup seasoned breadcrumbs, (for topping)
• fresh parsley or thyme for topping

How to Make French Onion Stuffed Shells

Step 1: Caramelize the Onions

Heat the butter in a large oven-safe skillet over medium heat. Stir in the onions with a pinch of salt, pepper, and thyme. It’s important to season each layer of cooking here! Cook, stirring often, until the onions caramelize, about 30 minutes. Be sure to watch them closely so they don’t burn! Turn down the heat if needed and continue to stir. Once caramelized, stir in the garlic. Turn off the heat once finished but leave them in the pan.

Step 2: Prepare the Pasta Shells

While the onions are cooking, bring a pot of salted water to a boil and cook the pasta shells according to the directions. Once cooked, drain them and place them on a baking sheet or plate to cool.

Step 3: Preheat Your Oven

Preheat your oven to 400 degrees F.

Step 4: Mix the Filling

In a bowl, stir together the ricotta cheese, egg, gruyere cheese, parmesan cheese, and a pinch of salt, pepper, and dried thyme. Take half of the caramelized onions from the pan and stir them into the ricotta mixture. This is your filling!

Step 5: Fill Each Shell

Fill each shell with the filling, stuffing it full but not overflowing.

Step 6: Make the Sauce

Turn the heat to medium-low under the remaining onions in the pan. Stir in the tablespoon of flour and cook for 1 to 2 minutes. Slowly stream in the stock while stirring. Cook for 2 to 3 minutes -the mixture will thicken a bit. Stir in the cream. Turn off the heat and place the shells open-side up in the French onion sauce. Top with mozzarella cheese and breadcrumbs.

Step 7: Bake It Up!

Bake for 20 to 25 minutes until golden and bubbly. Serve immediately with extra parmesan and fresh herbs on top.

Enjoy your delicious French Onion Stuffed Shells, perfect for any gathering or cozy night at home!

Common Mistakes to Avoid

When preparing French Onion Stuffed Shells, it’s easy to make mistakes that can affect the final dish. Here are some common pitfalls to watch out for:

• Not caramelizing onions properly: Skipping the caramelization step or rushing it can lead to bland flavors. Take your time to cook the onions until they are golden and sweet.
• Overcooking pasta shells: If you cook the shells too long, they can break while stuffing. Always follow the package instructions and aim for al dente.
• Skipping seasoning: Failing to season layers of ingredients can result in a flat taste. Remember to season every layer, especially the onion mixture.
• Using too much filling: Overstuffing the shells might cause them to spill over during baking. Fill them generously but avoid overflowing.
