Timing and Servings
You’ll need about 20 minutes to prep, then let your oven work its magic for 45 minutes. That gives you time to help with homework, catch up on emails, or just kick back with a cold drink. The recipe yields eight hearty portions—enough to feed a family, bring to a potluck, or freeze half for emergency dinners.
Ingredients
- 1 whole chicken (cut into 8 pieces) or about 4 cups shredded (rotisserie chicken works great)
- 1 pound thin spaghetti, broken into 2-inch lengths
- 2 cans (10¾ oz each) cream of mushroom soup (or cream of chicken for a milder flavor)
- 2¾ cups shredded sharp cheddar cheese, divided
- ¼ cup finely chopped green bell pepper
- ¼ cup finely chopped red bell pepper
- 1 medium onion, finely chopped
- 1 teaspoon seasoned salt
- 1⁄8–¼ teaspoon cayenne pepper, to taste
- Salt & freshly ground black pepper, to taste
- 2 cups reserved chicken broth (from cooking)
Odds are you’ve already got these on hand. If you’re feeling adventurous, toss in a handful of mushrooms or swap bell peppers for chopped celery or carrots.
Directions
- Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish.
- In a large pot, cover chicken pieces with water. Bring to a boil, then reduce heat and simmer for 30–45 minutes until tender.
- Remove chicken, reserving 2 cups of broth. Cool slightly, then shred, discarding skin and bones.
- Cook the broken spaghetti in the reserved broth until just al dente. Drain, keeping a splash of liquid for later if needed.
- In a large bowl, combine spaghetti, shredded chicken, soups, 1½ cups cheese, peppers, onion, seasoned salt, cayenne, and black pepper. Stir in 1 cup broth; add more if the mix seems dry.
- Transfer mixture into the casserole dish. Sprinkle the remaining 1¼ cups of cheddar evenly on top.
- Bake for about 45 minutes, until bubbly and lightly golden. If the cheese browns too fast, tent the dish with foil for the last 10–15 minutes.
- Let rest for 5 minutes before serving—this helps the cheese set and flavors meld.
Pro tip: don’t overcook the pasta in the broth. A firm bite holds up better once it’s baked.
Variations
- Swap cream of mushroom for cream of celery or chicken for a lighter taste.
- Add a cup of frozen peas, spinach, or chopped broccoli for extra color.
- Stir in artichoke hearts or sun-dried tomatoes for a Mediterranean twist.
- Use pepper jack cheese for a little kick, or gouda for a smoky note.
- Sprinkle taco seasoning into the mix for a Tex-Mex vibe—great with corn and black beans.
Storage & Reheating Tips
Allow the casserole to cool completely, then cover tightly. In the fridge, it lasts up to 2 days. To reheat, bake at 350°F for 20–25 minutes (covered) or microwave single servings.
Freezing? Wrap the whole dish in plastic and foil—good for up to 6 months. Thaw overnight before baking. For meal-prep, portion into airtight containers; just heat and eat.
FAQs
Can I use store-bought shredded rotisserie chicken? Absolutely. It saves time and adds a hint of seasoning.
What if I’m out of bell peppers? No sweat—celery, carrots, mushrooms or spinach all work just fine.
How spicy will it be? Only if you want it to be. Start with 1⁄8 teaspoon of cayenne, then taste and adjust.
Can I prep this the night before? Yes—assemble everything up to baking, cover, and chill for up to 24 hours. Then bake when you’re ready.
Is there a gluten-free option? For sure. Swap the spaghetti for a gluten-free variety and use a gluten-free cream soup.
