Flavor notes and swaps

The grated white cheddar gives this dish a bright, tangy cheese flavor. If you prefer a milder profile, swap part of the cheddar for a semi-soft cheese but keep the overall amount the same. The seasoned panko adds a pleasant crisp top; if you want a nutty crunch, toast some chopped almonds and mix them with the panko.

Step-by-step instructions

Preheat the oven and prepare the squash. Preheat your oven to 400°F (204°C). Slice the 2 spaghetti squash in half lengthwise and use a spoon to scrape out the seeds from each half. Pat the cut sides dry with a paper towel.
Season and roast the squash. Place the squash halves cut-side up on a baking sheet. Sprinkle each half with salt and pepper to taste. Roast in the preheated oven until the flesh is tender and can be easily shredded with a fork, about 35–45 minutes depending on squash size.
Cook the aromatics. While the squash roasts, heat 1 tablespoon olive oil in a medium skillet over medium heat. Add the diced shallot and sauté until softened and translucent, about 3–4 minutes. Add the 2 minced garlic cloves and cook for 30–60 seconds more, until fragrant. Stir frequently to prevent browning.
Steam the broccoli. Add the 3 cups broccoli florets to the skillet with the shallot and garlic. Cook, stirring occasionally, until the broccoli turns bright green and is just tender, about 4–6 minutes. If the skillet gets dry, add a splash of water and cover for a minute to help the broccoli steam.
Warm the milk and combine. Pour 1 cup milk into the skillet with the broccoli mixture and heat until warmed through but not boiling. Remove from heat and stir in 2 cups grated white cheddar cheese until melted and the sauce is smooth. Taste and season with additional salt and pepper if needed.
Shred the squash and prepare for stuffing. When the roasted squash halves are cool enough to handle, use a fork to shred the flesh into spaghetti-like strands. Transfer the strands into a mixing bowl, leaving the shells on the baking sheet or in an ovenproof dish for stuffing.
Combine squash and filling. Add the broccoli-cheddar mixture to the shredded squash in the mixing bowl and gently toss to combine, ensuring the cheese sauce and broccoli are evenly distributed throughout the squash strands.
Stuff the squash shells. Spoon the combined squash, broccoli, and cheddar mixture back into the roasted spaghetti squash shells, dividing the filling evenly between the 4 halves.
Add breadcrumbs and bake. Sprinkle a thin, even layer of ¼ cup seasoned panko breadcrumbs across the tops of the stuffed halves. Place the filled halves in an ovenproof dish if they aren’t already on one, and return to the oven. Bake at 400°F (204°C) for 8–12 minutes, until the breadcrumbs are golden and the filling is bubbling.
Rest and serve. Remove from the oven and let the stuffed squash rest for 3–5 minutes. Serve straight from the squash shells, and enjoy warm.

Serving suggestions

This Broccoli Cheddar Stuffed Spaghetti Squash stands well on its own as a satisfying main. Pair it with a crisp green salad dressed in lemon vinaigrette for brightness, or serve alongside roasted cherry tomatoes and crusty bread for soaking up any cheesy sauce. For an added protein boost, top each half with toasted chickpeas or a sprinkle of toasted walnuts.

Storage and reheating

Refrigerate any leftovers in an airtight container for up to 3 days.
To reheat, place stuffed halves in a 350°F (177°C) oven for 10–15 minutes until heated through and the topping is crisped. You can also microwave individual portions for 1–2 minutes, though the breadcrumb topping will soften.

Troubleshooting

If the squash takes much longer than 45 minutes to roast, check your oven temperature with an oven thermometer and slice the squash halves a bit thinner for faster cooking next time.
If the filling is too thin, stir in a tablespoon of cream cheese or a little more shredded cheddar to thicken it before stuffing.
If the broccoli is undercooked after stuffing, lightly steam it before folding into the cheese sauce so it finishes perfectly in the oven.

Final thoughts

Comforting and colorful, this Broccoli Cheddar Stuffed Spaghetti Squash is a love letter to simple, satisfying cooking. It’s adaptable, forgiving, and full of the kind of bright, cheesy flavors that feel like home. Make it when you want a dish that’s a little special but requires minimal fuss.

If you try this recipe, take a photo of that golden breadcrumb top and the stringy squash flesh — it’s one of those dishes that’s both wholesome and undeniably craveable.

Ingredients Equipment Method Notes

Ingredients

2 spaghetti squash halved, seeds scraped out
salt and pepper to taste
1 tablespoon olive oil divided
1 shallot diced
2 garlic cloves minced
3 cups broccoli florets
1 cup milk
2 cups white cheddar cheese grated, divided
1/4 cup seasoned panko breadcrumbs

Equipment

Baking Sheet
Aluminum Foil
Skillet
Spatula or wooden spoon
Mixing Spoon
Fork

Method

Preheat the oven to 400°F and line a baking sheet with foil; spray or lightly oil the foil.
Slice each spaghetti squash in half lengthwise and scrape out the seeds. Brush the cut sides with half of the olive oil and place cut-side down on the prepared baking sheet.
Roast the squash in the preheated oven for 25 minutes, or until the flesh is tender when pierced with a fork.
While the squash roasts, heat the remaining olive oil in a skillet over medium-low heat. Add the diced shallot and minced garlic and cook about 2 minutes until softened and fragrant.
Add the broccoli florets to the skillet and sauté, stirring often, for 6–8 minutes until slightly softened.
Pour in the milk and warm for 1–2 minutes, then stir in 1 cup of the grated white cheddar; remove from heat and stir until the cheese melts and the mixture is combined.
Remove the roasted squash from the oven and flip the halves cut-side up. Use a fork to loosen some of the squash strands, season with salt and pepper, then evenly divide the broccoli-cheddar mixture among the squash halves.
Sprinkle the remaining 1 cup of cheddar over each filled squash, then top with the seasoned panko breadcrumbs.
Return the stuffed squash to the oven and bake 10–15 minutes until the cheese is melted and golden and the breadcrumbs are lightly browned.
