- 1 lb cooked, shredded chicken: Perfect for adding heartiness and protein to the dish.
- 1 can Rotel tomatoes (diced): Adds a bright, spicy flavor that livens up the whole casserole.
- 1 can cream of chicken soup: Creates a luscious, creamy texture that binds everything together.
- 1 cup shredded cheese (cheddar or Mexican blend): Melts beautifully for that golden, cheesy crust.

- Salt and pepper to taste: Essential seasonings to balance and season every component.
How to Make Rotel Chicken Spaghetti Casserole Recipe
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 350°F (175°C). Lightly grease a baking dish to ensure your casserole doesn’t stick and cleans up easily after that delicious meal.
Step 2: Mix It All Up
In a large bowl, combine the cooked spaghetti, shredded chicken, canned Rotel tomatoes, cream of chicken soup, chicken broth, garlic powder, salt, and pepper. Stir gently but thoroughly so all those flavors marry together perfectly.
Step 3: Spread the Mixture
Pour this well-blended mixture into your prepared baking dish, spreading it out evenly so every bite has a uniform burst of flavor and texture.
Step 4: Cheese It Up
Generously sprinkle shredded cheese over the top. Whether you go with sharp cheddar or a Mexican blend, this layer is the crowning glory that melts into gooey perfection.
Step 5: Bake to Perfection
Place your dish in the oven and bake for about 25 to 30 minutes. What you’re looking for is bubbly edges and a beautifully browned cheese topping that signals it’s ready to make its grand entrance at your table.
Step 6: Let It Rest and Serve
Once out of the oven, give the casserole a few minutes to rest. This step allows the ingredients to settle so portions hold together nicely when scooped, making serving easier and more enjoyable.
How to Serve Rotel Chicken Spaghetti Casserole Recipe

Garnishes
Adding fresh garnish transforms your casserole into something truly special. Try topping it with chopped green onions, a sprinkle of fresh cilantro, or a dollop of sour cream to complement the creamy, spicy flavors.
Side Dishes
This casserole pairs beautifully with crisp green salads, steamed veggies, or a simple garlic bread to soak up every last bit of cheesy, tomatoey goodness.
Creative Ways to Present
If you want to impress guests, serve individual portions in mini ramekins topped with a fresh herb sprig. For a sharing-friendly option, place it in the middle of the table with colorful serving utensils to invite everyone to dig in.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftovers tightly and store them in the refrigerator. They’ll stay fresh for up to 3 days, making for a perfect next-day meal.
Freezing
You can freeze this casserole either before or after baking. Wrap it securely in foil and place it in an airtight container or freezer bag. It will keep well for up to 2 months, so you always have a comforting meal ready anytime.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through to maintain that cheesy crust and creamy texture, or microwave in short bursts stirring occasionally for a quicker fix.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely! Rotisserie chicken is a convenient and flavorful choice that pairs perfectly with the other ingredients in this Rotel Chicken Spaghetti Casserole Recipe.
Can I substitute a different pasta for spaghetti?
Yes! While spaghetti is traditional, feel free to use any pasta shape you have on hand, such as penne or elbow macaroni. Just keep in mind cooking times and textures may vary slightly.
Is this casserole very spicy?
The Rotel tomatoes add a gentle kick of heat, but it’s mild overall. You can tone down the spice by draining some of the liquid from the Rotel or omit the seeds before mixing.

What cheese works best in this casserole?
Cheddar or a Mexican blend are classics because they melt well and complement the savory and spicy flavors. However, feel free to experiment with Monterey Jack or mozzarella for a different twist.
