What You’ll Need
To prepare this casserole, you will need a medium spaghetti squash as your base, which is roasted to create tender strands. The filling consists of cooked chicken breast and drained Rotel tomatoes. The creamy, dairy-free sauce is built using Kite Hill cream cheese, unsweetened coconut milk, ghee, and nutritional yeast for a savory, cheesy finish.
Ingredient Notes
- Spaghetti squash – A medium squash around 2 pounds is the perfect size to provide enough strands for a hearty casserole base.
- Cooked chicken breast – Using pre-cooked and diced chicken makes the assembly process much faster; it stays tender as it bakes in the sauce.
- Rotel – These diced tomatoes with green chilies provide the signature zesty kick and a beautiful pop of color.
- Kite Hill cream cheese – This almond-based cream cheese provides a luxurious, dairy-free creaminess that melts beautifully into the sauce.
- Ghee – Adds a rich, buttery flavor and helps the sauce achieve a silky consistency.
- Canned coconut milk – Ensure you use the unsweetened version to provide a thick, creamy base without adding any sweetness.
- Nutritional yeast – This is the secret to achieving a savory, “cheesy” flavor profile in a completely dairy-free dish.
- Garlic and onion powder – These spices provide a concentrated savory depth that perfectly seasons the chicken and squash.
Add-ins and Substitutions
- Extra Spice – If you love heat, you can stir in a handful of diced fresh jalapenos or an extra pinch of crushed red pepper flakes.
- Vegetables – Feel free to fold in some sautéed bell peppers or steamed broccoli florets before the final bake.
- Protein Swap – While chicken is classic, this casserole also works wonderfully with ground turkey or even shredded rotisserie chicken.
- Toppings – For a bit of texture, you can sprinkle some crushed grain-free crackers or extra nutritional yeast over the top before it goes back into the oven.
How to Make Chicken Rotel Spaghetti Squash Casserole
- Prep the squash: Preheat your oven to 400F and coat a casserole dish with cooking spray. Slice the spaghetti squash in half lengthwise and scoop out the seeds and ribbing.
- Roast the squash: Drizzle the inside of the squash with olive oil and sprinkle with salt and pepper. Place the squash cut side down on a baking sheet and use a fork to poke holes in the skin. Roast for 30 to 40 minutes, or until the outside is lightly browned and the flesh is fork tender.
- Fluff the strands: Remove the squash from the oven and flip them over so they are cut side up. Once they are cool enough to touch, use a fork to scrape and fluff the strands from the sides. Place all the strands into a large mixing bowl.
- Prepare the sauce: Reduce the oven heat to 350F. In a large skillet over medium heat, add the bite-sized pieces of cooked chicken.
- Combine seasonings: Add the drained Rotel, dairy-free cream cheese, nutritional yeast, coconut milk, salt, pepper, ghee, and garlic and onion powders to the skillet. Heat for about 5 minutes, stirring until everything is fully combined and creamy.
- Mix and assemble: Transfer the warm chicken and sauce mixture into the bowl with the spaghetti squash strands. Mix thoroughly until the squash is evenly coated.
- Bake the casserole: Pour the mixture into a lightly greased 8×11 casserole dish. Bake at 350F for 30–40 minutes until the edges are bubbling and the casserole is heated through.
Pro Tip: To prevent the casserole from becoming watery, ensure your Rotel is drained very well and avoid over-roasting the spaghetti squash in the first step. You want the strands to be tender but still hold their shape so they don’t turn into a puree during the second bake.
Recipe Tips
- Poking the Squash – Poking holes in the skin of the squash allows steam to escape during the roasting process, which helps achieve a better texture.
- Squash Size – Since squash sizes vary, keep an eye on your roasting time. A smaller squash may be done in 30 minutes, while a larger one might need the full 40.
- Skillet Mixing – When heating the sauce ingredients in the skillet, use a whisk or spatula to break up the dairy-free cream cheese so it incorporates smoothly with the coconut milk.
- Casserole Dish Size – An 8×11 dish is ideal for this volume of ingredients, but a standard 9×9 square dish can also be used if needed.
FAQs
Can I use a different type of squash? Spaghetti squash is unique because it shreds into strands that mimic pasta. While other squashes like butternut or acorn are delicious, they will result in a much mashier texture and are not recommended for this specific casserole.
Is this dish spicy? The spice level is mild to medium, depending on the variety of Rotel you choose. Using “Original” Rotel provides a nice zesty flavor without being overly hot.
What if I don’t have nutritional yeast? Nutritional yeast provides the cheesy flavor in this dairy-free recipe. If you must omit it, the casserole will still be creamy but will have a milder, more savory profile rather than a cheesy one.
Serving Suggestions
- Side Salad – A crisp green salad with a zesty lime vinaigrette perfectly complements the creaminess of the casserole.
- Roasted Greens – Serve with a side of roasted asparagus or sautéed kale for extra nutrients.
- Avocado – Top each serving with fresh sliced avocado for added richness and a cooling contrast to the Rotel.
Make This Recipe in Advance

Ingredients
- 1 medium spaghetti squash (about 2 pounds)
- 1 tbsp olive oil
- 3 chicken breasts, cooked and diced
- 1 1/2 cans Rotel, drained very well
- 1 container Kite Hill dairy-free cream cheese
- 1/2 cup canned unsweetened coconut milk
- 1 tbsp ghee
- 3 tbsp nutritional yeast
- 1 tsp salt
- 1 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp pepper
Instructions
Step 1: Prep the Squash
Preheat your oven to 400F and coat a casserole dish with cooking spray. Slice the spaghetti squash in half lengthwise and scoop out the seeds and ribbing.
Step 2: Roast the Squash
Drizzle the inside of the squash with olive oil and sprinkle with salt and pepper. Place the squash cut side down on a baking sheet and use a fork to poke holes in the skin. Roast for 30 to 40 minutes, or until the outside is lightly browned and the flesh is fork tender.
Step 3: Fluff the Strands
Remove the squash from the oven and flip them over so they are cut side up. Once they are cool enough to touch, use a fork to scrape and fluff the strands from the sides. Place all the strands into a large mixing bowl.
Step 4: Prepare the Sauce
Reduce the oven heat to 350F. In a large skillet over medium heat, add the bite-sized pieces of cooked chicken.
Step 5: Combine Seasonings
Add the drained Rotel, dairy-free cream cheese, nutritional yeast, coconut milk, salt, pepper, ghee, and garlic and onion powders to the skillet. Heat for about 5 minutes, stirring until everything is fully combined and creamy.
Step 6: Mix and Assemble

Step 7: Bake the Casserole
Pour the mixture into a lightly greased 8×11 casserole dish. Bake at 350F for 30–40 minutes until the edges are bubbling and the casserole is heated through.
Notes
Preventing Wateriness: Spaghetti squash naturally holds a lot of moisture. To keep your casserole creamy rather than watery, ensure you drain the Rotel thoroughly and avoid over-roasting the squash; the strands should be tender-crisp (al dente) before the second bake.
Storage and Reheating: This casserole stores beautifully in the refrigerator for 3 to 4 days. For the best texture, reheat in a 350F oven for 15 minutes to restore the bubbling edges, or microwave individual portions as needed.
Flavor Variations: For extra depth, try blooming your spices in the ghee for 30 seconds before adding the coconut milk. If you prefer more heat, use the Hot variety of Rotel or add a pinch of crushed red pepper flakes.
