Total Time: 1 hour 30 minutes
Servings: 6-8
Dietary Type: Comfort Food

Ingredients

8 chicken thighs or 6 chicken breasts
Olive oil
Butter
1 small onion, diced small, or 8 white pearl onions
2 garlic cloves, diced
Salt
Pepper
1 (10 ounce) can cream of mushroom soup
4 medium-sized ripe tomatoes, diced
1/4 cup chopped bell pepper (optional)
2 teaspoons parsley (optional)
1 (8 ounce) can tomato sauce
1 1/2 cups shredded Italian cheeses (mozzarella, Parmesan, and asiago recommended)
1 (10 ounce) bag frozen peas, partially thawed
3 tablespoons flour
12 ounces spaghetti, broken in half (& cooked for 6-7 minutes)

Equipment Needed

Large glass baking dish
Large pot
Saucepan or skillet
Colander

Instructions

Begin by thawing the chicken completely. This will ensure even cooking.
Butter (or oil) a large glass baking dish generously. This will prevent sticking and make serving easier.
Place the chicken in the prepared dish.
Melt 1/3 cup butter (or substitute margarine or oil) and slather it generously over the chicken. This will add richness and flavor.
Dash salt and pepper onto the chicken to taste. Don’t be shy; seasoning is key!
Sprinkle uncooked garlic and onion over the chicken, using as much as you like. The aromatics will infuse the chicken with flavor as it bakes.
Bake at 425°F (220°C) for 20 minutes. This initial bake will get the chicken cooking while you prepare the other components of the casserole.
While the chicken is baking, fill a large pot with water and bring it to a boil for the spaghetti. Add a dash of salt and oil to the water (the oil helps prevent the spaghetti from sticking). Cover the pot to speed up the boiling process.
Add the spaghetti, broken in half, to the boiling water and cook for 6-7 minutes. You want the spaghetti to be al dente since it will continue to cook in the casserole.
Drain the spaghetti in a colander and rinse with cold water. This stops the cooking process and prevents the spaghetti from becoming mushy. Set aside.
In a saucepan (or skillet), sauté the onions and garlic in oil over medium heat until they are slightly browned and softened. This will release their flavors and add depth to the sauce.
Add the cream of mushroom soup to the sautéed onions and garlic, and stir to combine.
Add the diced tomatoes, bell pepper (if using), parsley (if using), and partially thawed green peas to the saucepan.
Add the tomato sauce and stir to combine all the ingredients.
Cook for 2-3 minutes, allowing the flavors to meld together.
Add the shredded Italian cheese and stir until it is completely melted and incorporated into the sauce, creating a creamy, cheesy base.
Add the flour and stir to thicken the sauce. This will help bind the casserole together.
Cover the saucepan and cook until the sauce is thickened (about 4-6 minutes), stirring often to prevent sticking and burning.
Remove the chicken from the oven and transfer it to a separate dish to cool slightly.
Set aside the baking dish to cool (and while the chicken is cooling and the sauce is simmering, clean the baking dish and re-butter/oil it; you’ll reuse it for the finished casserole).
Once the chicken has cooled enough to handle, tear it off the bone and shred it to your desired consistency.
In the prepared casserole dish, mix together the shredded chicken, the sauce, and the cooked spaghetti. Ensure everything is well combined.
Top the casserole with additional Parmesan cheese. This will create a golden-brown, cheesy crust.
Bake at 425°F (220°C) for 45 minutes, or until the casserole is bubbly and the top is golden brown.

Expert Tips & Tricks

To save time, use pre-cooked rotisserie chicken instead of baking the chicken thighs or breasts.
If you prefer a spicier casserole, add a pinch of red pepper flakes to the sauce.
For an even richer flavor, use a combination of cream of mushroom and cream of chicken soup.
If your sauce is too thick, add a splash of milk or chicken broth to thin it out.
To prevent the top of the casserole from browning too quickly, cover it loosely with foil during the last 15-20 minutes of baking.

Serving & Storage Suggestions

Serve the Shredded Chicken & Spaghetti Casserole hot from the oven. A simple green salad or steamed vegetables make a perfect accompaniment.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in individual portions. For freezing, cool the casserole completely, then wrap tightly in plastic wrap and aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
