Vegetarian Skillet Stuffed Shells

This is SO good! It does take a bit of time but is totally worth it. One pan, cooks on the stove, makes plenty for dinner and some leftovers (at least in our family). The shells are stuffed with a mixture of mushrooms, spinach, and ricotta; while the recipe calls for crimini mushrooms I used a mixture of two different kinds of mushrooms because that's what I could get in the amount I needed.

Skillet Stuffed Shells

serves 4-6

 

18 jumbo pasta shells

 1 1/2 tsp kosher salt, divided

2 Tbsp olive oil

1/2 lb crimini mushrooms, thinly sliced

1 tsp freshly ground black pepper

1/2 c dry white wine

5 oz. baby spinach

6 cloves garlic, thinly sliced

2 Tbsp unsalted butter

3 c marinara sauce

1/2 tsp crushed red pepper flakes

2 c ricotta

3 oz finely grated Parmesan (about 1 cup), more for serving

2 tsp dried oregano

Cook shells in a large pot of boiling water, stirring occasionally until very al dente, about 9 minutes; drain. Run under cold water to stop the cooking; drain again.

Meanwhile, heat oil in a large skillet over high. Add mushrooms and cook stirring occasionally, until they release juices, then are dry again and nicely browned, 5-6 minutes; season with black pepper and 1 tsp salt. Reduce heat to medium, add wine, cook stirring until reduced by half, 1-2 minutes. Add spinach, cover and cook until beginning to wilt, 1-2 minutes. Uncover and continue to cook, stirring occasionally until spinach is completely wilted and most of the liquid is evaporated, 2-4 minutes more. Transfer mushroom mixture to a large bowl.

Cook garlic and butter in the same skillet over medium-high heat, stirring occasionally until garlic is fragrant and beginning to brown, 2-3 minutes. Add marinara sauce and red pepper and bring to a simmer over low heat. Cook stirring occasionally until warmed through, 6-8 minutes.

While sauce cooks, add ricotta, 3 oz Parmesan, oregano, and remaining 1/2 tsp salt to the mushroom mixture and stir to combine. Spoon about 2 Tbsp of mixture into each shell. The shell should be filled to capacity but not overstuffed.

Nestle stuffed shells into hot sauce in skillet. Cover and cook over medium heat until shells are warmed through, 4-6 minutes. Remove from heat and let sit 5 minutes. Sprinkle with Parmesan, serve.
