Baked Rutabaga Spaghetti and Mozzarella

When you think about tomato sauce and cheese, what’s missing?


Well, today, you get it all – tomato sauce, basil, cheese, and rutabaga spaghetti.

This is one of those servable dishes that your family and friends will beg you to make over and over again.

The mozzarella cheese is gooey enough to satisfy our cheese craving, the tomato sauce is bubbly and fragrant with the basil, and the rutabaga spaghetti mimics the exact texture of real spaghetti, except it has a beautiful nutty flavor that brings out the sweetness in the tomatoes AND of course, it’s gluten-free and a vegetable!

Baked Rutabaga Spaghetti and Mozzarella

When you divide this dish up, you can do it two ways: split it up into 6 big portions, or treat each mozzarella slice as a “serving” and in that case, you’ll get 9 servings out of this dish (for instance, if you want to serve it to kids who don’t eat as much as us adults or if you’re serving it as a side dish, alongside salad or something like that.)

Whatever way you serve it up, this spaghetti bake has all those classic Italian flavors – garlic, basil, tomatoes, mozzarella and won’t send your blood sugar spiking, thanks to the use of the spiralized rutabaga!

Baked Rutabaga Spaghetti and Mozzarella

Prep Time15 mins
Cook Time55 mins
Total Time1 hr 10 mins
Servings: 6


  • 2 cans 28oz whole peeled tomatoes
  • 2 medium rutabagas peeled, Blade D, noodles trimmed
  • salt and pepper
  • 1 tablespoon extra virgin olive oil
  • 2 garlic cloves minced
  • 2 cups packed basil leaves
  • 9 ¼ ” slices of fresh mozzarella cheese


  • Preheat the oven to 400 degrees.
  • In a food processor, pulse tomatoes until coarsely chopped.
  • Meanwhile, heat a large non-stick skillet over medium-high heat. Once heated, add the rutabaga noodles, season with salt and pepper and cook until wilted and cooked through, about 15 minutes. You may need to do this in batches. Once cooked, set aside in a large mixing bowl.
  • Place the skillet back over medium-high heat and add the oil. Once oil is shimmering, add the garlic and cook until fragrant, about 30 seconds. Add the tomatoes and bring to a boil. Lower the heat to medium and let cook at a solid simmer until sauce thickens, 12-15 minutes.
  • In the large mixing bowl with the rutabaga, add the prepared tomato sauce, basil, and half the mozzarella and toss to combine. Transfer the mixture to a 3-quart baking dish and top with the remaining cheese. Bake in the oven until cheese is golden and edges are bubbling, about 25 minutes.
  • Serve immediately.

Maureen says:
Any substitution ideas for the rutabaga?
Ali Maffucci says:
Regular potato, sweet potato, butternut squash (it may break up a bit though), kohlrabi, and parsnip if you can find enough large parsnips !
maureen oberle says:
Thanks for the ideas. Sometimes it's hard to find rutabaga
Karen says:
Ali, is the nutritional breakdown information based on the 6-serving option or the 9-serving one? I'll be trying the recipe soon — dinner doesn't get any easier than this!
Ali Maffucci says:
It's for 6 servings!
Rebecca says:
What is the large pot of salted water in step 2 used for? Is it a mistake?
Ali Maffucci says:
The error has been corrected!
Lisa says:
When it says to add half the mozzarella, do I need more than the 9 slices that are going on top of the dish? Thanks -- love your recipes!
Maura says:
Was wondering the same thing - from the look of the picture of the recipe, you need 9 slices for the top.
DJ Aiken says:
I saw this recipe yesterday. Stopped off at the store on my way home to pick up needed items (who has rutabaga in their pantry?) and made this for dinner last night. Totally awesome! I would give it 5+ stars on a 1-5 rating system. I am not particularly fond of rutabaga, but this was the perfect vegetable for this dish! And, Ali is correct in saying it is just like pasta with a bit of a nutty flavor. I always love to "tweak" a recipe, but only after I have tried it as written. Next time, I might tweak it with some Andouille sausage and maybe some capers, but, the recipe, as given is absolutely yummy!
Kelly says:
Hi Ali! Any reccomendations for spiralizing a rutabaga ? I tried with blade D and it came out all stuck together like chips. I moved up to a larger blade and that worked perfectly. Any tips for the future !?
Stephanie says:
Thanks for this comment! I had the same problem, but then I sat there and separated out the spirals by hand. I didn't think of changing to a different setting. Is it because the rutabaga is so hard, or what? I made a variation of this recipe and it was delicious! I added a spiralized onion into the sauce, and liked that addition. I think next time I may add some tomato paste to thicken up the sauce a bit.
Lucy says:
Can I assemble earlier in the day and then cook for dinner, or will noodles be too soggy?
Lucy says:
I'm making this today, so guess I should have asked this earlier in order to get a response! Any opinions from anyone?
Heidy says:
I tried this recipe yesterday. I did the sauce a bit differently, using canned chopped tomatoes and tomato paste just because of what was in the pantry, but essentially followed your recipe. The family loved it and it is definitely a keeper ( I never imagined we would ever eat rutabaga!). Also, it fits into our lower carb vegetarian diet and re-heats beautifully. Thank you so much!
Sue says:
Any ideas how this could be adapted for a slow cooker? I love coming home and find out someone has been thoughtful enough to make us dinner! (Even though the someone is me, the house smells great and we're ready to eat!) Thanks for your wonderful recipes, they help us eat healthy!
Anonymous says:
Made this last night for dinner and it is truly incredible! My husband adored it and did not miss the meat at all. My favorite part is the delicate crunch in the noodles! This will definitely be on repeat in the household. Thank you Ali for this gem! Also ditched my paderno this morning for a Inspiralizer I ordered on Amazon and I am so excited to get it.
KristineD says:
This recipe was quick and delicious! I halved the recipe, since I don't need 6-9 servings to myself. Instead of whole stewed tomatoes, I used a can of Hunt's fire-roasted diced tomatoes. As they were simmering in the pot, I used a potato-masher to pulverize them instead of getting my food processor dirty. I added some Simek's turkey meatballs to the casserole pan for baking. Perfection!

hi! 👋🏼 just checking in! twins are doing so well, their little personalities are really shining through. and they’re getting so big, they barely fit on my chest together anymore 😭😭 (rio is almost 11 pounds and sol is almost 10!) they’re sleeping almost 5 hours at night which gives me some rest in between nursing sessions (if I’m lucky enough that one of my older kids doesn’t wake up in between that time 🤦🏻‍♀️.) as for me, I’m coming out of the newborn fog 🙏🏼 the hardest part has been dividing my time between all FOUR of my kids, honestly. I’ll never get it right 😏 today I had my 6 week postpartum check up and I guess everything is back where it’s supposed to go 😅 because I got the green light to resume normal life again, but can we be honest…. with twin newborns, I’m in no rush to 🏋🏻‍♀️ or 🍆 , ya know? ...

the soup that broke the internet! 😜🥣haha, just kidding, but after posting this on stories, my DMs were flooded with, "share the recipe!" and then dozens of you made the soup solely based off my story videos (which is why I shared it!)⁣ 👏🏼

I'm still deep in the newborn fog to take proper photos and build an SEO-friendly blog post (it's an hours-long process), so I'm sharing it here in the meantime - just save it to refer back to! you're going to want to make this alllll winter long.⁣ ❄️

potato and brussels sprouts white bean soup w/ or w/o chicken sausage⁣ 👇🏼
serves 4-6

3 tablespoons extra virgin olive oil⁣
1/2 red onion, diced⁣
2 garlic cloves, minced⁣
2 carrots, diced⁣
1 large celery rib, diced⁣
1 15-ounce can cannellini beans, drained and rinsed⁣
1/2 teaspoon dried rosemary⁣
1/2 teaspoon dried thyme⁣
4 cups vegetable broth (I'm using @bonafideprovisions and it's honestly a game-changer! code INSPIRALIZED for 15% off!)⁣
salt and pepper⁣
1 1/2 pound bag creamer potatoes, halved⁣
1 pound chicken sausage, sliced⁣
12 ounces shredded brussels sprouts⁣
shredded Parmesan cheese (I'm loving @foragerproject's vegan Parmesan shreds)⁣
red pepper flakes to garnish⁣

heat half the olive oil in a large pot over medium-high heat. add the onion, garlic, carrots, and celery and cook for 5 minutes or until onions are translucent. add the cannellini beans, rosemary, thyme, and stir. add the broth, 2 cups water, and season generously with salt and pepper. bring to a boil and boil for 5 minutes. use an immersion blender to blend the soup. add the potatoes, bring back to a boil, and reduce heat to a medium-simmer and let cook for 10 to 15 minutes or until potatoes are tender.⁣

while potatoes cook, heat the remaining oil in a large skillet over medium heat. add the chicken sausage and cook until browned. add the brussels sprouts, season with salt and pepper, and cook until sprouts are tender and chicken is cooked through. keep aside. if you're vegetarian, just simply omit chicken sausage.⁣

once potatoes are done, add the chicken and sprouts to the soup, stir, and serve. top with cheese and red pepper flakes.
