Total Time	35-45 minutes
Level of Difficulty	Medium

Ingredients

For the casserole:

• 12 oz small pasta shapes (like Ditalini or elbow macaroni)
• 1/2 tsp black pepper (freshly ground is best)
• 1 cup frozen peas (thawed)
• 1 cup shredded mozzarella cheese
• 1/2 tsp salt

For assembly:

• 1 batch homemade mushroom soup (recipe linked in description)

Step 1: Preheat Oven and Prepare Ingredients

Begin by preheating your oven to 375 degrees F.

Next, prepare a batch of Cream of Mushroom Soup following the recipe found here: Homemade Cream of Mushroom Soup Recipe.

Step 2: Cook the Pasta

While the soup simmers, bring a large pot of salted water to a boil.

Cook your pasta for 1 minute less than the package instructions indicate, as the pasta will continue to cook in the oven.

Drain the pasta, reserving about ½ cup of the cooking water.

Step 3: Combine Ingredients

In a large mixing bowl, stir together the prepared cream of mushroom soup, salt, pepper, frozen peas, and ½ cup of shredded mozzarella cheese.

Mix in the cooked pasta, along with 2 tablespoons of the reserved pasta cooking water.

If you find that the mixture is too thick, or if you’re preparing the casserole a day ahead for leftovers, add additional pasta cooking water, 1 tablespoon at a time, until you reach the desired consistency.

Taste the mixture and adjust the salt and pepper as needed.

Step 4: Assemble the Casserole

Transfer the pasta mixture to a casserole dish, spreading it out evenly.

Sprinkle the remaining ½ cup of shredded mozzarella cheese over the top of the mixture.

Step 5: Bake the Casserole

Bake the casserole, uncovered, in the preheated 375 degree F oven for 20-25 minutes, or until the cheese on top is bubbly and slightly browned.

Remove from the oven and let it cool slightly before serving.

Enjoy your delicious casserole!
