Pasta Shells stuffed with spinach, mushrooms, and tomatoes

EASY SPINACH STUFFED PASTA SHELLS

Pasta shells stuffed with a cheesy spinach and mushroom mixture is the ultimate comfort dinner, and it’s SO easy to make.

Stuffed shells are a fun and tasty option for pasta night, but also a clever way to sneak in some good-for-you veggies. Covered and masked in cheese, of course. 

Baked on a bed of flavorful marinara until cheesy and bubbly, these simple stuffed shells are great for a family dinner or even a pot luck. It makes a lot of filling that holds up well, and you’ll be able to stuff around 20 shells.

HOW TO MAKE STUFFED SHELLS WITH SPINACH

…OR FLORENTINE, which is a fancy way of saying a recipe that features spinach

  • Cook pasta shells according to package directions. I advise to undercook them a bit, or cook to al dente, because the shells will finish cooking in the oven. If you overcook, they will tear and fall apart.
  • While pasta is cooking, prepare the filling: In a large skillet, cook the mushrooms for 5 minutes.
  • Then, add drained diced tomatoes, some seasonings, and finally baby spinach. Since we’re using a lot of spinach, you will want to cook it in batches. As soon as one batch is cooked down, add the next – I break it up into 3 batches.
  • Coat the bottom of a 9×13 baking dish with marinara sauce.
  • Stuff the prepared shells with the spinach filling, and arrange them over the marinara sauce in the baking dish.
  • Sprinkle mozzarella cheese all over the pasta shells. 
  • Bake in a 350F preheated oven for 20 to 25 minutes, or until bubbly.
  • Serve.

Pasta shells stuffed with spinach mushroom sauce

This dish is so amazing because it can feed an army, and because of its very few layers of ingredients. There’s tomatoes, there’s spinach, lots of garlic, meaty mushrooms, and cheese.

If, for some reason, you are not a fan of mushrooms (WHAT?!?), leave them out. You can add ground meat instead, but I would suggest to reconsider – ‘shrooms are good!

  1. Mushrooms are so good! Despite being a cheese fan I had never cared for the usual ricotta filling unseen in stuffed shells but I dig this. Btw your pal Mojito has been hanging out with my pal Manhattan;)

  2. Haha I love the “what?!” for the mushrooms-who does NOT love mushrooms? Weird! 🙂

    This dish looks awesome-people at work thought I was Italian because of all the pasta I always bring lol.

  3. Stuffed shells can make a pretty impressive pasta dish even though the ingredients are pretty straight forward. I really should buy a package one of these days.
