Meatball stuffed acorn squash is comfort food that looks like it took all day to make.
Italian turkey meatballs in a simple marinara, piled into roasted acorn squash and finished under a blanket of bubbly cheese. It’s cozy, a little impressive, and naturally low carb. Serve it straight from the broiler while the cheese is still bubbling and it’s comfort food at its finest.
It’s the Day 2 dinner in my free 3-day low-carb meal plan, and it hides one of my favorite no-waste tricks in the whole plan.
Turkey Meatball Stuffed Acorn Squash (Low-Carb Comfort Food)
Equipment
- Rimmed baking sheet
- Sauce pan
- Conventional Oven
Ingredients
- 1 lb Festive Italian style ground turkey
- 1/2 Yellow onion
- 2 cloves Garlic
- 1 tbsp Butter
- 1 can Great Value Italian-style petite diced tomatoes with basil, garlic and oregano (14.5 oz)
- 3 oz Grated Colby Jack cheese (or Italian style cheese)
- 1/2 Acorn squash
Instructions
Form the meatballs
Form the turkey into bite-size meatballs. I use small meatballs here for two reasons: they're much easier to eat once they're tucked into the acorn squash, and the smaller size means they cook more quickly — making this recipe a little more weeknight-friendly.Bake the meatballs
Place the meatballs on a rimmed baking sheet and bake in an oven-style air fryer or conventional oven at 325°F for about 20 minutes. They don't need to be completely cooked through at this point because they'll finish cooking in the sauce.Make the sauce
While the meatballs bake, sauté ½ diced yellow onion in 1 tablespoon butter with a pinch of salt. Once the onion has softened, about 5–10 minutes, add 2 minced cloves of garlic and cook until fragrant.Add 1 can of Italian-style petite diced tomatoes with basil, garlic, and oregano.Prep the squash
While the sauce cooks, slice the acorn squash in half and scoop out the seeds. We're cooking both halves of the squash here. We'll remove some of the meaty part of the squash later to make room for meatballs.Finish the sauce
Let the sauce simmer over medium-low heat until the tomato pieces have softened. If you prefer a smoother sauce, use an immersion blender or food processor to blend the tomatoes and onions to your desired consistency.Add the meatballs to the sauce
Once the meatballs have finished baking, transfer them to the hot tomato sauce. Reduce the heat to low and let the meatballs finish cooking in the sauce.Bake the squash
Use a spoon or basting brush to brush some of the juices that cooked out of the meatballs over the cut surface of the acorn squash.Place the squash cut-side down on a rimmed baking sheet and bake at 400°F for about 30–45 minutes. I used the same baking sheet I used for the meatballs — I just gave it a quick wipe with a paper towel first.Make room in the squash
Once the acorn squash is fully cooked — a fork inserted into the flesh should meet almost no resistance — scoop out about half of the squash to make room for the meatballs and sauce.If you're making this as part of my free 3-day meal plan, set the scooped-out squash aside for tomorrow's dinner: Shepherd's Pie.Assemble and broil
Pile the cooked meatballs and sauce into the hollowed-out acorn squash, then top with grated cheese. Place under the broiler for a few minutes, keeping a close eye on it. Broiling can go from perfectly melted to burned very quickly.If you don't have a broiler or your baking dish isn't broiler-safe, bake at 400°F until the cheese is melted and bubbly.

Cutting the squash (the honest hard part)
I won’t pretend acorn squash is easy to cut — that ridged shell is tough, and it’s where people nick themselves. The safest move: slice a thin sliver off one end so the squash sits flat and won’t roll, then cut down through a groove. If your knife fights you, microwave the whole squash for about three minutes to soften it first. I filmed how I cut mine without losing a finger.
A note about the 80-minute cook time
I’ll be honest: about 1 hour and 20 minutes from start to finish can be a stretch on a weeknight. The good news is that most of that time isn’t hands-on cooking. The squash spends 30–45 minutes roasting, and the meatballs take about 20 minutes to bake, so there’s plenty of time when the oven is doing the work for you. I spent most of the time the squash was cooking scrolling my phone, catching up on posts.
If you’re really pressed for time, there’s an easy way to get ahead: roast the squash as part of your prep day when you’re making the quiche and enchilada casserole. It can bake alongside either one while the oven is already on. Then refrigerate it until you’re ready to assemble this dinner.
So I wouldn’t call this a 30-minute weeknight dinner — it isn’t. But it’s also not 75 minutes of standing at the stove. It’s a good one for a night when you’re home, watching a movie or binging your favorite series, and have the time to let dinner take care of itself.
The trick: one squash, two dinners
Here’s the part I love. If you’re doing this as part of my free 3-day meal plan, when you scoop out the roasted squash to make room for the meatballs, you don’t toss that flesh — you save it. The next night, it becomes the creamy, flour-free topping for the shepherd’s pie. One acorn squash, two dinners, nothing in the trash. That’s the whole philosophy of this plan in a single move.
- Makes: 2 servings (Day 2 dinner for two)
- Cost: about $1.65 a serving as part of the under-$30 plan
- Equipment: baking sheet · saucepan · oven
Serve it up
Serve each stuffed half hot, straight from the broiler while the cheese is still bubbling. It’s a full, satisfying plate on its own — no side needed — and the roasted squash’s sweetness pairs beautiful with the savory meatballs and marinara.
A fair criticism of the meatballs
The meatballs in this recipe are quite dense. I don’t add any binders or breading because most breading is super carby, high in gluten, or costly and I try to stay low-carb, gluten-free, and budget-friendly. By just cooking the meatballs with no other ingredients, other than seasoning added, I keep the cost and carbs low and keep everything free of gluten.
There are a couple ways to get around this if you prefer lighter meatballs:
- You can add a binder that suits your budget and dietary preferences.
- You can make a simple ragu by browning up the meat in the same pot you make your sauce rather than forming the meat into balls.
Meatballs are fun but I think a simple ragu would work perfectly here. Whatever your preference, you have options.
Love the squash-and-meatball combo? My spaghetti squash with meatballs and marinara is another way to do it.
Does it have to be turkey?
Absolutely not! I used turkey here because of the very budget friendly price point on the Festive brand Italian style ground turkey. Plus, since the meat is already seasoned, I didn’t need to add any flavor to these, which also helps with keeping everything in budget.
But this could be made with any kind of ground meat, a combo of ground meats, or your favorite meal alternative.
