Oh my gosh, you have to try this sausage pasta with Brussels sprouts and butternut squash – it’s my go-to when I want something hearty but don’t feel like fussing all night in the kitchen. The first time I threw these ingredients together, I couldn’t believe how perfectly the smoky sausage played with the sweet squash and those crispy little Brussels sprouts. After tweaking the recipe through probably a dozen test batches (my neighbors got very familiar with my “experiments”), I landed on this foolproof version that balances all the flavors just right.

Ingredients for Sausage Pasta Brussels Sprouts Butternut Squash
Okay, here’s the magic lineup – and yes, measuring matters here because we want those flavors perfectly balanced! Trust me, I learned that the hard way when I once eyeballed the garlic (let’s just say… it was an intense dinner).
For the Roasted Veggies:
- 3 cups butternut squash – peeled, seeded, and cubed into ½-inch pieces (about 1 small squash)
- 12 oz Brussels sprouts – trimmed and halved (quarter any big ones so they cook evenly)
- 3 tbsp olive oil – divided (we’ll use 1 tbsp for the squash, 2 for the sprouts)
- Salt and pepper – don’t be shy here; roasted veggies need proper seasoning!
For the Pasta & Protein:
- 8 oz bow tie pasta – or whatever short pasta you’ve got (those little ridges hold sauce beautifully)
- 12 oz smoked sausage – I use pre-cooked Andouille for that extra kick, sliced into coins
- 1 tbsp olive oil – for sautéing the sausage (it’ll pick up all those tasty browned bits)
The Flavor Boosters:
- 5 cloves garlic – minced (or more if you’re a garlic fiend like me)
- 2 tbsp butter – because everything’s better with butter
- ¼ tsp smoked paprika – optional but SO good with the sausage
- Fresh thyme – for garnish (those little leaves make it look fancy with zero effort)

How to Make Sausage Pasta Brussels Sprouts Butternut Squash
Alright, let’s get cooking! This dish comes together in stages, but don’t worry – I’ve timed it all out so everything finishes perfectly together. The secret is getting those veggies beautifully roasted while the pasta cooks, then bringing it all together at the end.
Roasting the Vegetables
First, crank your oven to 400°F – and don’t skip the preheat! I learned the hard way that cold ovens make for soggy veggies. Line two baking sheets with parchment paper (trust me, cleanup is a breeze this way).
Toss your cubed butternut squash with 1 tablespoon olive oil, plus a good pinch of salt and pepper. Spread them out on one sheet – don’t crowd them or they’ll steam instead of roast. Pop those in the oven first since they take a bit longer, about 15-20 minutes. You’ll know they’re done when the edges get golden and you can easily pierce them with a fork.
While the squash is roasting, toss your halved Brussels sprouts with the remaining 2 tablespoons olive oil and more salt and pepper. Spread these on the second sheet and roast for about 20-30 minutes – you want those outer leaves to get crispy and caramelized. Oh, that smell when they start to brown? Absolute heaven!
Cook the Pasta and Sausage
While the veggies work their magic, bring a big pot of salted water to boil for the pasta. Cook your bow ties (or whatever shape you’re using) just until al dente – usually about 1 minute less than the package says. Reserve about ½ cup of that starchy pasta water before draining – it’s liquid gold for adjusting your sauce later!
In your largest skillet (I use my trusty cast iron), heat 1 tablespoon olive oil over medium-high. Add those sliced sausages in a single layer – don’t crowd them! Let them get a good sear for about 5 minutes per side until they’re nicely browned. That caramelization equals flavor, my friend.
Combining Everything
Now for the grand finale! In the same skillet (keep all those tasty browned bits), melt your butter over medium heat. Add the minced garlic and cook just until fragrant – about 1 minute. Don’t let it burn! Toss in the drained pasta, stirring to coat in that garlicky butter goodness.
Gently fold in your roasted squash, Brussels sprouts, and sausage. If things look a little dry, add a splash of that reserved pasta water. Finish with a sprinkle of smoked paprika if you’re using it, and toss in some fresh thyme leaves. Taste and adjust seasoning – sometimes I add an extra pinch of salt at this stage.

Tips for Perfect Sausage Pasta Brussels Sprouts Butternut Squash
Want to take this dish from good to “Oh wow!”? Here are my tried-and-true tricks:
Cut veggies evenly – I aim for ½-inch squash cubes and halved Brussels sprouts (quartered if they’re big). This way everything roasts at the same rate without some pieces turning to mush while others stay crunchy.
Get that skillet screaming hot before adding sausage – a proper sear equals maximum flavor. I test mine by flicking a drop of water – if it sizzles instantly, we’re golden.
Fresh thyme makes all the difference as a garnish. Just strip the leaves by running your fingers down the stem – no chopping needed! The subtle herbal note brightens up the whole dish.
Don’t skip the pasta water reserve – that starchy liquid is magic for bringing the sauce together if things get too dry during the final toss.

Variations for Sausage Pasta Brussels Sprouts Butternut Squash
The beauty of this dish? It’s practically begging for customization! Here are my favorite twists:
- Sweet potato instead of squash – just cube and roast the same way, though they might cook a smidge faster
- Turkey or chicken sausage for a lighter option (though you’ll miss some of that smoky punch)
- Gluten-free pasta works great – I’ve had success with brown rice fusilli holding the sauce well
- Add some heat with red pepper flakes or cayenne if your sausage isn’t spicy enough

Serving Suggestions
This sausage pasta is a complete meal on its own, but I love pairing it with garlic bread to soak up every last bit of that buttery sauce. For a lighter touch, toss together a simple arugula salad with lemon vinaigrette. The recipe makes four generous portions – just enough for seconds (because let’s be real, you’ll want them!).

Storage and Reheating
Leftovers? Lucky you! This sausage pasta keeps beautifully in an airtight container for up to 3 days – though mine never lasts that long. When reheating, I prefer the skillet method: just toss everything with a splash of water over medium heat until warmed through. The microwave works in a pinch too, but stir halfway to keep things from drying out. Pro tip: those Brussels sprouts stay crispier if you reheat them separately and mix in at the end!

Frequently Asked Questions
Can I use raw sausage instead of pre-cooked?
Absolutely! Raw sausage works fine – just slice and cook it thoroughly (until no longer pink) before adding to the pasta. I prefer pre-cooked because it’s quicker and less messy, but fresh sausage gives you that extra crispiness if you’ve got the time.
What’s the best pasta shape for this dish?
Bow ties are my favorite because those little ruffles catch all the buttery sauce and roasted veggie bits perfectly. That said, any short pasta with grooves or ridges works great – penne, fusilli, or even rigatoni would be delicious. Just avoid super delicate shapes that might get overwhelmed by the hearty ingredients.
Can I prep the vegetables ahead of time?
You can chop everything in advance, but I recommend roasting the veggies day-of for maximum crispiness. Pre-roasted squash tends to get mushy, and Brussels sprouts lose that wonderful caramelized edge. Trust me, the extra 30 minutes of roasting time makes all the difference in texture!
