- Prep Time: 10 minutes
- Cook Time: 1 hour and 10 minutes
- Total Time: 1 hour and 10 minutes
- Yield: 6 1x
- Category: Dinner
- Cuisine: gluten-free, paleo, whole30
Ingredients
- 5 cups cooked spaghetti squash
- 2 cups shredded chicken (rotisserie chicken or make it)
- 1 green bell pepper, diced
- 1 red pepper, diced
- 1 yellow onion, diced
- 2 cups spinach, loosely packed
- 1 batch refried beans (or buy it)
Enchilada Sauce:
- 2 tablespoons avocado oil or extra-virgin olive oil
- 2 tablespoons arrowroot flour
- 1 tablespoon chili powder
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon ground cumin
- 1/2 teaspoon fine sea salt
- 1/2 cup Tuttorosso Tomato Sauce
- 1 cup chicken broth
To garnish:
- Chopped cilantro, for garnish
- Chopped scallions, for garnish
- Optional: 1/4 cup Mexican blend cheese, more for topping
Instructions
- If you don’t already have spaghetti squash cooked, start by doing that: Preheat oven to 375ºF and line a baking sheet with foil or parchment paper. Cut spaghetti squash in half, lengthwise. Scoop out seeds. Brush inside with oil. Place facedown on baking sheet and add 1 tablespoon or so of water to the baking sheet. Bake for 45-50 minutes, or until you can pierce with a fork. Once done, scrape out squash into spaghetti stands and set aside. See this article for more info on cooking spaghetti squash.
- While cooking, sauté the veggies: Over medium heat, add 1 tablespoon oil and sauté onions and peppers for 5-8 minutes until soft. Add in spinach and mix to wilt. Set aside.
- Make the Enchilada Sauce: In a small saucepan over medium-high heat, heat the oil. Add the arrowroot flour and stir together over the heat constantly for 1 minute. Stir in the chili powder, garlic powder, onion powder, cumin, and salt. Then add the tomato sauce and gradually add the chicken broth, whisking to remove any clumps. Reduce the heat and let simmer for 10 minutes or until the sauce thickens. Taste and adjust any spice as desired.
- Assemble and Bake: Preheat oven to 350ºF. In a large bowl combine cooked spaghetti squash, shredded chicken, sautéed veggies, refried beans, enchilada sauce, and optional cheese. Spread evenly into a greased baking dish and top with additional optional cheese. Bake for 20-30 minutes until cheese is bubbly. Garnish and serve.
Notes
Omit cheese and beans for dairy-free, paleo, and Whole30-compliant!

So excited for this! Going to try the squash in instant pot. I usually just poke a buncha holes in the squash and bake it whole…easier for me to cut.
Looks delicious! Just did a chicken on the grill so half-way there!
I will try that idea!!
love all that melty gooey cheese!!
I dont have arrow root flour on hand. Almond flour ok?
Almond won’t work – tapioca would.
This is what I like to call heathy comfort food for the win! Looks so delicious!
Can I substitute coconut flour in place of arrow root flour??
NO! That won’t work. Tapioca would be the replacement 🙂
This looks perfect for dinner!
Made this tonight. I did the chicken and squash in the Instantpot. It was delicious. I won’t ever need to buy premade enchilada sauce or refried beans again. I was not a spaghetti squash eater before.
I used almond flour and it worked perfectly! Great recipe! Delicious
Made this last night! It was amazing. Even my boys gobbled it up. I did both squash and chicken in the instant pot. (So easy)! I substituted black beans for the refried because I was running out of time and it’s what I had on hand. I will never buy store bought Enchilada sauce again! So easy and delicious. Looking forward to trying it with the refried beans next time. So yummy!!! Even better the next day with eggs!
This looks delicious! Does everything need to be hot when assembled for baking or would it be possble to prep some of these components ahead?
Prep spaghetti squash and chicken ahead!!
OMG…I am actually drooling over this dish! Looks fab 🙂
I made this on Friday and it was full of flavor. The enchilada sauce is key to the flavor as it has much more flavor then the canned sauce you would easily substitute when reading the recipe. The refried beans could be substituted with can, but again making them as outlined above added to the flavor. It came together pretty quickly once all the ingredients were ready to go. Using rotisserie chicken makes it easier as this is a longer prep recipe with the sauce and beans but really came together quickly. I did use the optional cheese but it’s really not necessary. Can’t wait to eat the leftovers.
Probably my favorite of Lexi’s recipes I’ve made! I omitted the cheese and it was still creamy and delicious! It’s hard to get my husband behind something with this many veggies but he loved it too! I’ll definitley be making it again.
SO glad it was a hit!
Made this today…major snow storm here so I used kale and riced cauliflower because I had no peppers or spinach. My daughter makes happy noises when she eats something good (it is really cute) and she is mmm, mmm, mming as we speak. I was going to skip the beans, but it adds the best layer, and the sauce…OH MY! Such a winner, Lexi…many gold stars for you!!!
Sounds amazing! Is this something you could make the night before to through in the oven the next day or will the ingredients become too soggy?

I made this last night and we love it!!!
It’s soooo good! Our kids are ages 3, 5, 7 and 9. They don’t usually eat all that well but they loved this soo much and had seconds and thirds. Our 7 year old said “Mom we have to have this all the time!”
Thank you!!!
★★★★★
What a lovely recipe! Thank you for sharing it, I bet this casserole is super delicious!
★★★★★
Delicious!!! I made this last night and was alittle nervous with all the steps and prep but it ended up being soo easy. I can’t wait to make it again and I had plenty of leftovers to bring for lunch today at work.

Hello this recipe looks delicious however would you be kind enough to list the nutrition breakdown? Thank you, Valerie
Can you tell me the calories per serving
We are working on adding nutrition data. In the mean time, use any free online calorie calculator like Myfitnesspal!
Can’t wait to make this! Weird question; what brand is your saucepan? Is it cast iron or just black rimmed?
I love my Le Creuset skillet! http://amzn.to/2FByguC
This was absolutely amazing! I cooked the squash in the Instapot and it turned out perfect. The enchilada sauce was to die for in and of itself. My husband and kids all enjoyed it
★★★★★
Hi Lexi! Do you make this in an 8×8 size baking dish or a 9×13?
Made this last night, and it’s so good! I left out the chicken, and left some of the black beans whole for texture. I used cotija cheese instead of a blend, and served it with lactose free sour cream. It had so much flavor! It’s definitely being added to my regular rotation.
★★★★★
Going to make tonight. This may be a crazy question but I already bought the squash shredded.. Do I need to warm that up first or just put in the mix as is ? ( I don’t own a microwave)
If it’s shredded, just toss it with the rest of the ingredients!
Made this a few nights ago for me and my gluten-free husband. Used a couple of shortcuts – leftover refried beans and Frontera red enchilada sauce. It came out great and was different frm the usual Italian style casseroles. It’s a keeper – Thanks!

How many spaghetti squashes do I need to make 5 cups?
It really depends on the size of the squash you get – I know that’s not a great answer. Roughly 3-4 pound squash would be our best guess.
Can It be assembled in the morning, refrigerated and baked for a luncheon that day? Also can I make refried beans night before?
Yes to both!
Do you think this could be frozen? Either before or after baking to prepare for a new baby? Thanks!
I think it could be frozen after being baked, but there might be some extra water released after reheating due to the spaghetti squash. As long as you don’t mind that, think it could work!
