How to Make Cheesy Spinach and Mushroom Stuffed Shells Step-by-Step

Creating this dish may seem layered (pun intended), but it’s more straightforward than you think. Break it down into these easy steps, and you’ll have a golden, gooey tray of stuffed shells on your table in no time.

---

1. Preheat and Prep

Set your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. This ensures your cheese sauce doesn’t stick and clean-up is a breeze.

---

2. Cook the Mushrooms to Golden Perfection

In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add your sliced mushrooms in a single layer and let them cook without stirring for 5 minutes. This is the key to that golden-brown sear.

Now toss in the dried thyme, salt, and pepper. Let them sauté for another 4-5 minutes until they’re fragrant and tender. Once done, remove from heat and set aside.

---

3. Craft Your Velvety Cheese Sauce

Using the same saucepan, melt the remaining 6 tablespoons of butter. Add the chopped garlic, basil, and oregano—let it bloom for 30 seconds.

Next, whisk in the flour and stir continuously for about a minute. Slowly pour in the wine (or broth), followed by the milk. Keep stirring until the mixture starts to bubble. Remove it from heat and stir in half of your mozzarella and Parmesan until smooth and luscious.

---

4. Boil the Pasta Shells

Cook the shells in salted boiling water according to the package directions. Be sure to keep them al dente—they’ll finish cooking in the oven. Drain and lay them out on a flat surface to cool slightly before filling.

---

5. Mix the Creamy Ricotta Filling

In a large mixing bowl, combine the ricotta, shredded provolone, and well-drained spinach. This rich, creamy mixture is the heart of every bite.

---

6. Assemble Your Dish

Layer your baking dish with:

1. Bottom layer: One-third of the cheese sauce
2. Stuff the shells: Use a spoon to fill each shell with about 1 tablespoon of the ricotta-spinach mix
3. Arrange: Place the filled shells in the dish
4. Top: Sprinkle with the remaining mozzarella
5. Pour over: The remaining cheese sauce
6. Finish: Scatter the cooked mushrooms and a sprinkle of Parmesan on top

---

7. Bake to Bubbly Bliss

Cover with foil and bake for 25 minutes. Remove the foil and bake for another 15-20 minutes until the top is golden and bubbling.

---

8. Serve and Garnish

If you like, add fresh thyme for an aromatic finish. Serve hot—and get ready for compliments.
