Cheesy Mushroom Chicken Spaghetti: A Comfort Food Classic

There’s something undeniably comforting about a warm casserole, especially when it’s brimming with cheesy goodness and familiar flavors. I remember one particularly blustery autumn evening, coming in from the cold, and my grandmother had this exact dish waiting. The aroma alone, a blend of savory chicken, earthy mushrooms, and creamy cheese, was enough to thaw me from the inside out. One bite, and I was transported to a place of warmth and contentment. It’s a dish that speaks of home, family, and simple pleasures, and I’m thrilled to share my version of it with you.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 40 minutes
• Total Time: 1 hour
• Servings: 8
• Yield: One 2 1/2 Quart Casserole
• Dietary Type: Not Gluten-Free

Ingredients

• 1 (10 3/4 ounce) can condensed cheddar cheese soup
• 1 (10 3/4 ounce) can condensed cream of mushroom soup
• 1 (10 3/4 ounce) can Ro-Tel diced tomatoes with peppers, undrained
• 1 (16 ounce) package Velveeta cheese
• 8 ounces thin spaghetti
• 1/2 cup mushroom, chopped
• 1/2 cup onion, chopped
• 2 tablespoons butter
• 3 cups roasted chicken breast, cubed
• 1 tablespoon garlic salt
• 1 tablespoon black pepper

Equipment Needed

• Large pot
• Large skillet
• Cutting board
• Knife
• Large casserole dish (2 1/2 quart)

Instructions

1. Begin by preparing your ingredients. Cut the roasted chicken breast into rough cubes, about 1 inch in size. Then, finely chop the mushrooms and onions.
2. In a large skillet, melt the butter over medium-high heat. Once melted, add the chopped mushrooms and onions and sauté until they are softened, about 5-7 minutes.
3. Add the cubed chicken, garlic salt, and black pepper to the skillet with the softened mushrooms and onions. Mix well to combine, ensuring the chicken is evenly seasoned.
4. While the chicken and mushroom mixture is cooking, bring a large pot of water to a rolling boil. Add the spaghetti and cook for about 8 minutes, or until it is slightly underdone (al dente). Remember that the spaghetti will continue to cook in the oven, so it’s best to slightly undercook it at this stage to prevent it from becoming mushy.
5. Once the spaghetti is cooked, drain it completely in a colander.
6. Chop the block of Velveeta cheese into approximately 1-inch cubes. This will help it melt more evenly into the casserole.
7. In a large casserole dish, combine the condensed cheddar cheese soup, condensed cream of mushroom soup, undrained can of Ro-Tel diced tomatoes with peppers, cubed Velveeta cheese, and the chicken mixture. Mix well to combine all the ingredients.
8. Add the drained spaghetti to the casserole dish and mix thoroughly, ensuring that the pasta is evenly coated with the cheese and chicken mixture. Be mindful while mixing, as the Velveeta cubes can sometimes clump together, especially after warming up from the hot pasta.
9. Cover the casserole dish with a lid or aluminum foil and bake in a preheated oven at 350 degrees Fahrenheit for 30 minutes.
10. After 30 minutes, remove the cover (if you prefer a crispy top). Bake for an additional 10 minutes, or until the top is golden brown and bubbly. If you prefer a softer top, leave the casserole covered for the entire baking time.
11. Once the casserole is done, remove it from the oven and let it cool for about 10 minutes before serving. This will allow the cheese to set slightly and prevent it from being too runny.

Expert Tips & Tricks

• Roasting your own chicken will add even more flavor to this dish. Leftover roasted chicken is perfect!
• If you want to add some extra vegetables, consider including diced bell peppers or frozen peas to the chicken mixture.
• For a spicier kick, use the “Hot” version of Ro-Tel tomatoes.
• To prevent the pasta from sticking together while waiting, you can toss it with a tablespoon of olive oil after draining.
• If the casserole seems too thick, add a splash of milk or chicken broth to loosen it up.

Serving & Storage Suggestions

This Cheesy Mushroom Chicken Spaghetti is best served warm, straight from the oven. A simple side salad with a light vinaigrette complements the richness of the casserole perfectly. Garnish with some fresh parsley for added color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions until heated through. You can also reheat the entire casserole in a preheated oven at 350 degrees Fahrenheit until warmed through. If the casserole appears dry after reheating, add a splash of milk or broth to restore its creamy consistency. I do not recommend leaving this dish at room temperature for more than two hours due to dairy content. Freezing is possible for up to 2 months. Thaw overnight in the fridge before reheating.

FAQs (Frequently Asked Questions)

Q: Can I make this casserole ahead of time?
A: Absolutely! You can assemble the casserole completely, cover it tightly, and store it in the refrigerator for up to 24 hours before baking. Add about 10-15 minutes to the baking time if baking directly from the refrigerator.

Q: Can I freeze this casserole?
A: Yes, you can freeze this casserole either before or after baking. For best results, wrap it tightly in plastic wrap and then in aluminum foil. It can be stored in the freezer for up to 2 months. Thaw completely in the refrigerator before baking or reheating.

Q: Can I use a different type of pasta?
A: While thin spaghetti works best, you can use other types of pasta such as rotini, penne, or elbow macaroni. Adjust the cooking time according to the package directions.

Q: Can I use fresh tomatoes instead of Ro-Tel?
A: Yes, you can use fresh diced tomatoes. However, Ro-Tel tomatoes add a unique flavor and a slight kick, so you may want to add a pinch of cayenne pepper to mimic the flavor.

Q: My casserole is too dry. What can I do?
A: If the casserole seems too dry, add a splash of milk, chicken broth, or even a little sour cream to moisten it up. Mix well before baking or reheating.
