I know I’ve done a ton of pasta-related stuff lately. For those that don’t follow the blog regularly, I’ve been posting spinach and three cheese manicotti and lasagna roll-ups. But they’re so good for these upcoming cold days and everyone loves a good Alfredo.

So today I’ve tweaked my chicken Alfredo pasta bake to make it more vegetarian friendly and for those who love tortellini. The great thing about this variation is you can skip the cooking time for the pasta because you don’t have to cook the tortellini beforehand.

This tortellini Alfredo spinach casserole has spinach, tons of meaty, baby portabella mushrooms and a ton of melty, creamy cheese. Smothered in a creamy Alfredo sauce mixed with ricotta cheese and topped with a mozzarella cheesy top, this casserole should comfortably feed about 8-10 people.

It’s super, super-rich, so have a light side ready to balance it out! The best part about this bubbly, warm casserole is all you need to make it are simple, store-bought ingredients. No fancy pasta makers or 20-minutes of sauce making. Let’s start cooking.

TORTELLINI ALFREDO SPINACH CASSEROLE RECIPE TIPS

This was the first time I’ve played around with frozen tortellini and the package said 4 minutes was all it took to cook. So applying the same no-boil concept I used with my spinach and artichoke ravioli bake, I decided it had plenty of time to cook in the oven and did not need pre-boiling. You’ll want a bag of frozen ravioli, which I found pretty easily in the frozen section. Thaw it just a little in the fridge so they don’t stick together.

Cook the frozen spinach in the microwave and while you’re doing that, start chopping the mushrooms. It’ll look like a lot of mushrooms but don’t worry. They’ll cook down and shrink in size along the way, leaving plenty of room for the pasta.

We’ll be sauteing the mushrooms on the stove beforehand because they tend to release some liquid once cooked and we don’t want that diluting the casserole. It’s the same reason we’ll use a mesh strainer or something similar to squeeze out as much liquid from the cooked spinach as possible. Long story short: excess liquid = bad!

It’s easy from here on out. Mix the slightly thawed tortellini with the Alfredo sauce (you can use store-bought or make your own) and add the cooked mushrooms and spinach and some sour cream. Season it too. You probably won’t need much salt because the Alfredo sauce will take care of that.

Then we make the ricotta mix with good quality ricotta cheese (I used the Galbani brand it makes a HUGE difference!), garlic, egg, Parmesan and parsley. Then we mix the ricotta mixture with the tortellini mixture. It’ll make squishy, cheesy noises and you’ll start feeling guilty but that’s okay. Once in a while, right? Not every day!

Pour the pasta mixture into a 9×13 casserole dish and top with mozzarella cheese. You don’t need to cover this while baking so just bake it for 30 minutes or so and get the cheese on top to brown by finishing off with a quick broil on the top rack.

Once that’s done, it’s ready to serve. Happy eating and let me know how you liked it in the comments below.

    Loved your recipe! I swapped out a couple of the ingredients (what I had in the freezer) but the basic recipe was the same. I used chopped broccoli for the spinach and ground sweet Italian sausage for the mushrooms. Delicious! Thank you!!

      A casserole is always a great excuse to empty out the fridge. I’m a big fan of Italian sausage and it’s a wonderful substitution 🙂 Thanks for sharing your substitutions, Mary Beth!

        One day ahead should be fine. Keep it covered and refrigerated. Good luck!

    So enjoyed this new pasta version of Alfredo even though I managed to leave the spinach in the microwave!! I don’t at all feel guilty for devouring so much protein in one meal.

      Aww to the spinach but I’m glad the food still worked out. Maybe I should leave instructions to not forget them in the microwave? 😉

      It’s swimming in cheese-related sauces and toppings! Not something I’d recommend eating on a day to day basis but for crummy and cold bad days when you need some comforting pick-me-up food, this should do it!

    Hi Farah! What a deliciously simple dish! All I would have to buy is the tortellini! I almost always have fresh mushrooms on hand and, if I don’t, I have a bag of really nice assorted dried mushrooms.

      Dried mushrooms will work great if you rehydrate them and get rid of all water content! And this recipe was made especially for folks that wanna just get it all from the grocery store and have it all ready. Super easy!

    Regarding the Tortellini Alfredo Spinach Casserole We enjoyed this dish. Easy to make. Even my picky-eater 95-year-old mother-in-law liked it. Since there are only three of us I cut ingredients in half and that worked out fine.
