- Add More Veggies: Feel free to toss in any vegetables you have on hand, like spinach, zucchini, or mushrooms. The more, the merrier!
- Flavor Adventure: If you love spice, add some red pepper flakes or diced jalapeños for a kick to the flavor profile.

Your Spaghetti Squash Casserole Recipe
Ingredients
- 1 large spaghetti squash
- 2-3 large chicken breasts (about 1.25 pounds)
- 1 tablespoon Italian seasoning
- 1/2 teaspoon salt
- 1 medium green bell pepper, diced
- 6 ounces diced tomatoes (drained, about 2/3 cup)
- 1 (10.5 ounce) can cream of mushroom soup
- 1/4 cup plain Greek yogurt
- 1 teaspoon minced garlic
- 2 cups shredded cheese (divided – mozzarella or cheddar work great)
- 2 tablespoons chopped fresh basil or chives (optional)
Instructions
- Preheat the Oven: First things first, preheat your oven to 400°F (200°C). We want to get it nice and toasty for our casserole.
- Prepare the Spaghetti Squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. This is where the magic happens!
- Set Up the Baking Pan: Fill a baking pan with a 1/4 inch layer of water and place the spaghetti squash halves face down in the pan—trust me, this helps it cook evenly.
- Season the Chicken: Grab a large 9×13 inch casserole dish, place the chicken breasts inside, and sprinkle the Italian seasoning and salt on top.
- Bake Everything: Place the baking pan with spaghetti squash and the casserole dish with chicken in the oven at the same time. Bake for about 45-50 minutes—until the squash is soft and the chicken is cooked through.
- Prepare the Rest: While they’re baking, dice that green bell pepper and drain the diced tomatoes. Simple steps, but they make a big difference!
- Mix it Up: Once the chicken is done, shred it up into bite-sized pieces. Also, use a fork to pull out the “spaghetti” strands from the squash and add them into the casserole dish.
- Combine Everything: Toss in the green bell pepper, drained diced tomatoes, cream of mushroom soup, Greek yogurt, minced garlic, and 1 cup of your shredded cheese. Mix it all together until wonderfully combined.
- Top with Cheese: Sprinkle the remaining 1 cup of shredded cheese over the mix. You know we love that cheesy goodness!
- Lower Oven Temperature: Reduce the oven heat to 350°F (175°C) and pop the casserole back in for another 15-20 minutes, until everything is heated through and the cheese has melted beautifully.
- Garnish and Serve: Take that casserole out of the oven and let it cool slightly. If you want, sprinkle some chopped fresh basil or chives on top for a pop of color and flavor, then serve warm. Enjoy every cheesy, flavorful bite!
Practical & Valuable Tips
- Cool It Down: Let the casserole sit for a few minutes after taking it out of the oven. It helps everything set up a bit and makes serving easier.
- Storage: Store any leftovers in an airtight container in the fridge. It will stay good for 3-5 days—if it lasts that long!
- Reheating: To reheat, place it in the oven at 350°F (175°C) until warmed through, or do a quick microwave zap if you’re short on time.
- Freezing: If you want to make this ahead, you can freeze the assembled casserole before baking, just add a little extra time in the oven when you decide to bake it!
- Fun Serving Ideas: Pair it with a crisp green salad for a lovely complete meal—great for balancing flavors.
Equipment You’ll Need
Here’s a handy list of items you should have in your kitchen to whip up this recipe:

Frequently Asked Questions
- Can I use frozen chicken breasts? Yes! Just adjust the cooking time, as frozen chicken will take a bit longer to cook through. Ensure it reaches 165°F (75°C) at the thickest part.
- What if I don’t have Greek yogurt? You can use sour cream or even a bit of cream cheese as an alternative for creaminess!
- How do I know the spaghetti squash is fully cooked? It should be soft when pierced with a fork. The strands inside should easily pull apart.
- Can I add other spices? Absolutely! Feel free to add your favorite herbs or spices to enhance the flavor according to your taste.
- What’s the best cheese to use? While mozzarella and cheddar are great, you can also explore gouda or provolone for a different flavor twist!
