How to Make French Onion Stuffed Shells
-
Caramelize the Onions: Heat the butter in a large oven-safe skillet over medium heat. Add the sliced onions with a pinch of kosher salt, pepper, and thyme. Cook, stirring often, until the onions are wonderfully caramelized, about 30 minutes, then stir in the minced garlic and turn off the heat.
-
Cook the Pasta: While the onions are caramelizing, bring a pot of salted water to a boil. Add the jumbo pasta shells and cook according to package directions until al dente. Once done, drain the shells and let them cool on a baking sheet or plate.

Preheat the Oven: Set your oven to 400°F (200°C) so it’s ready for baking these delicious shells.

Stuff the Shells: Take each cooled pasta shell and fill them generously with the cheesy onion mixture, being careful not to overstuff.
-
Make the Sauce: Return to the skillet with the remaining onions. Set the heat to medium-low, then stir in the flour and cook for 1 to 2 minutes. Gradually add the stock while stirring, cooking for 2 to 3 minutes until the sauce thickens, then finish with cream and turn off the heat. Place the stuffed shells open-side up in the sauce and sprinkle with mozzarella cheese and breadcrumbs.
