Everything you love about Stuffed Mushrooms in Casserole form. Where are my Stuffed Mushroom lovers at? You are going to LOVE this simple dinner! What took me so long to make something like this?! Stuffed mushrooms are one of my favorite foods in the world, and this casserole is a KEEPER! If you are a fellow mushroom lover, I’ve got a Stuffed Meatloaf recipe you’ve got to try! Get these both on your shopping list ASAP. You won’t regret it!
I love to use the hot Italian sausage in stuffed mushrooms for a little kick, so that is what I used in this casserole, too. Feel free to use mild if you prefer mild. Heck, even breakfast sausage would still taste great in this recipe, but the Italian spices in the sausage really add something.
My choice of egg noodles was also intentional. I wanted a soft, simple textured noodle because I thought it would pair best with the other ingredients. However, if you don’t have egg noodles, I think medium-sized shells or even spiral noodles would be a great option for a substitution.
The flavors in this casserole are so good. I am truly so excited to share this recipe. I can’t wait to hear how you like it!

Frequently Asked Questions for making Stuffed Mushroom Casserole
Can I make this casserole with Rice instead of Pasta?
If you want to make it all rice instead of pasta, I suggest reducing the chicken stock to 1 cup, and then making it up to the point where you would add the pasta. And just serve that mixture over the top of steamed rice and sprinkle cheese over it. Yum! That actually sounds delicious. I think I’m going to have to try that.
Do I have to bake this in the oven or can I just eat it like a skillet meal?
Technically, everything is fully cooked before baking. So you could definitely just add the cheese on top and eat it like a skillet meal. I like to bake it so the breadcrumbs get toasty and the cheese gets bubbly and browned.
What type of sausage is best to use in this recipe?
I prefer to use Hot Italian Sausage, but any type of sausage will work. You can use mild Italian, regular sausage, breakfast sausage…whatever you like.
what type of mushrooms work best in this recipe?
White Button or Cremini are the best mushroom options for this recipe.
Can I use half and half instead of whole milk?
Yes, you can use half and half. It will just be a titch less creamy, but still delicious and a great way to cut out a few calories.
