Why You’ll Love This Stuffed Shells Pasta Bake

These beef stuffed shells are loaded with flavour. You’ll love it!

What You’ll Need

jumbo pasta shells — I love the jumbo ones! It takes less time to stuff the jumbo ones than the smaller ones.
ground beef — I use lean ground beef, so I don’t have to drain any liquid when browning.
salt & pepper
garlic
onion — a small yellow onion is what I use. However, you can use any onion you have on hand.
mushrooms — I dice up two portobello mushrooms, but you can use baby bellas or white mushrooms.
baby spinach — I prefer baby spinach as they’re a little sweeter than regular spinach.
marinara sauce — use your favorite! You can also make your own marinara sauce if you’d like.
tomato paste — if you are using tomato paste from a can, you can freeze what you don’t use!
ricotta — I like using ricotta made with 100% whole milk.
mozzarella — shredding cheese from a block tends to melt nicer than bags of pre-shredded cheese as they tend to be coated in an anti-clumping powder.
parmesan cheese — again, I prefer to shred my own parmesan.
egg — to help bind everything together.
dried basil — if you’ve got fresh, great! But I use dried basil as it’s always in my pantry.

How to Make Stuffed Shells

Adding diced onions, garlic, and mushrooms into a skillet of beef.

Heat oven to 350F.
Bring a pot of salted water to a boil.
In a skillet, brown the beef, seasoning with salt and pepper. Once 80% browned, add in diced onions, minced garlic, and diced mushrooms. Sauté for 2-3 minutes.

Adding tomato paste, marinara sauce, and spinach to the skillet.

Add in ¾ cup marinara sauce, tomato paste, and baby spinach. Simmer for 10 minutes. Stirring throughout.
Add the jumbo pasta shells to the boiling water and cook for 1 minute before it’s al dente (my package says it takes 10 minutes to cook, so I cooked mine for 9 minutes, yours may vary).

Meanwhile, in a large bowl, combine the ricotta cheese, mozzarella, parmesan, egg, and dried basil. Mix to combine.
Drain the water from the pasta when done.
Once the sauce and beef have done simmering, add it to the cheese mixture. Stir to combine.

In a 12¼ by 8¼ baking dish, spray with some non-stick and then spread 1 cup of marinara sauce on the bottom.

Let cool before serving.

Tips and Notes

The jumbo shells will cook in the oven, which is why I suggest cooking 1 minute less than directed on the package.
Be sure to cover as much of your pasta shells as you can with either pasta sauce or cheese before baking. While it may look prettier with the shells on display, the shells will dry out in the oven if they’re exposed. I do let a little peak through because I like a little crunch but only a little bit!
I use a tablespoon to easily stuff my shells.
You can use a 9×13 dish if you prefer. I have both, and it fits perfectly fine. A bit more snug in the 12¼ by 8¼ baking dish, but it fits!

Make Ahead Tips

Meal prep: store the cooked lasagna stuffed shells in an airtight container for up to 4 days in the fridge.
Freezer: allow the stuffed shells to cool before transferring them into an airtight container and storing them in the freezer.
How to prep this for the freezer: pack the lasagna stuffed shells in a freezer friendly container that can go directly into the oven. Instead of baking it, cover it, and store it in your freezer. This way, you can directly bake it from frozen without risking thermal shock to your casserole dish. Freeze for up to 3 months. When ready, bake directly from frozen at 350F for 40 to 50 minutes, covered with a greased piece of tinfoil. Uncover and broil for 1 to 2 minutes at the end if the cheese needs a little help.
