Chicken Tetrazzini (Cotton Country) - cooking recipe

Ingredients

1 (8 ounce) package spaghetti
1/2 cup butter
1 onion, chopped
1 cup chopped celery (optional)
3/4 cup chopped bell pepper
1 (10.75 ounce) can condensed cream of mushroom soup
1 cup shredded sharp Cheddar cheese
1 tablespoon all-purpose flour
2 (14.5 ounce) cans chicken broth
2 cups chopped cooked chicken, or to taste
1/2 cup toasted slivered almonds
1 (4 ounce) can sliced mushrooms, drained
1 (2 ounce) jar chopped pimento peppers
1 teaspoon salt
1/2 teaspoon celery salt
1/2 cup crushed buttery round crackers (such as Ritz(R)), or as needed

Preparation

Preheat oven to 400 degrees F (200 degrees C).
Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally, until cooked through but firm to the bite, about 12 minutes. Drain.
Melt butter in a large skillet over medium-high heat; saute onion, celery, and bell pepper in hot butter until softened and translucent, 5 to 10 minutes. Whisk mushroom soup, Cheddar cheese, and flour into onion mixture until cheese melts and mixture is smooth. Add broth and stir until smooth.
Stir chicken, cooked spaghetti, almonds, mushrooms, pimento peppers, salt, and celery salt into cheese mixture. Pour into an 11x13-inch baking dish and sprinkle crushed buttery round crackers over the top.
Bake in the preheated oven until golden and bubbling, 15 to 20 minutes.
