Comfort Food Recipe
I love a good comfort food dish! Casseroles are definitely in this category for me.
This Cream of Mushroom Casserole is filled with simple ingredients like veggies, cheese, noodles. Your whole family will love it!
Whether you call this classic, traditional, old school, old-fashioned, country, or from scratch, this delicious noodle main dish is simple and easy to make, and is pure comfort food.
Comfort food that’s easy to make.
We’ve had lots going on in my family lately, so I’ve been falling back on some casseroles.
You make a big batch of something, and then you get to eat leftovers for a few days. I mean, what could be better!
In fact, I was making casseroles when the football playoffs were going on. I’d make the casserole on Friday, then we didn’t even have to miss any of the games on Saturday or Sunday.
And, not that everyone is all in when there are games on, but this idea works well for any sport that you don’t want to miss on TV, or any award show, or movie night as well!
If you want to make this casserole in advance, add in a little extra pasta cooking water.
The pasta will soak up the liquid as it bakes, and as it’s refrigerated.
So, I like to add in a little extra moisture to keep things creamy.
This Casserole starts with homemade condensed Cream of Mushroom Soup.

Cream of Mushroom Casserole Recipe
Cream of Mushroom Casserole
- 1 recipe Homemade Cream of Mushroom Soup
- 12 ounces small shape pasta like penne, shells, or Farfalle
- ½ teaspoon salt
- ½ teaspoon pepper
- 1 cup frozen peas thawed
- 1 cup shredded mozzarella
- Preheat oven to 375 degrees F.
- Make the Cream of Mushroom Soup (recipe here https://lifecurrentsblog.com/homemade-cream-of-mushroom-soup/ ).
- While soup simmers bring a large pot of salted water to a boil and cook pasta, cooking pasta for 1 minute less than the package instructions (pasta will continue to cook in the oven). Drain pasta, reserving about ½ cup of cooking water.
- Stir cream of mushroom soup, salt, pepper, frozen peas, and ½ cup of shredded mozzarella together. Mix in the pasta. Mix in 2 tablespoons of pasta cooking water. If mixture seems too thick, or if you’re making casserole a day before for leftovers, stir in additional pasta cooking water 1 tablespoon at a time until desired consistency is reached. Taste for salt and pepper.
- Place mixture in a casserole dish, and sprinkle remaining ½ cup shredded mozzarella over the top.
- Bake casserole, uncovered, in 375 degree oven for 20-25 minutes, or until cheese is bubbly and browned a bit.

This is a great use of your mushroom soup and that cheese topping, oh my.
I love that this uses homemade cream of mushroom soup! I’m not a fan of the canned stuff, but it’s used in so many casseroles. This looks absolutely fantastic. So cheesy and yummy. The pasta water is a great tip. I’ll have to try it the next time I have a pasta casserole!
This looks so comforting. I love that it’s vegetarian. I’m always on the lookout for more veggie meals for my family.
I’m not sure what I’m more excited about the homemade mushroom soup or this dish! Best of both worlds. Looks so yummy.
Glad you made this with homemade soup. Can’t bear the canned kind. It really does look deliciously appetising
I cannot believe this gorgeous dish is made with so few ingredients! My family will go crazy for this! 😀 Do you think it would be good to add some sausage or ham?
Unicorns, I think it would be lovely with ham or sausage. For me, I’d add a veggie sausage… mmmm! I would love adding big slices of mushrooms to it as well, but alas, the husband wouldn’t go for that!
There are loads of great comfort food dishes floating around these days, but I have to say, this one is the most amazing looking one I’ve seen. I can only imagine how incredible it tastes!
This looks perfect for our cold winter weather; thanks for the great inspiration!
Now that’s good food! I love that your using your own mushroom soup recipe! isn’t it nice that once you get going on some homemade recipes they work so well in so many other? I just love that. And I love that cheesy crusty top! Yum!
I would so much want this for my dinner tonight! It looks so creamy and packed with flavors!
This looks super tasty and perfect for my family dinner
