Keto Sheet Pan Sausage and Veggies

What You’ll Need

This dish keeps it simple with a short list of fresh, flavorful ingredients:

  • Smoked kielbasa sausage: Savory with just the right amount of smokiness.
  • Colorful veggies: Think diced butternut squash, zucchini half-moons, bright bell peppers (yellow or red), and thick slices of red onion.
  • Olive oil: For roasting and flavor.
  • Seasonings: A sprinkle of dried thyme, smoked paprika, garlic salt, and black pepper ties it all together.

Don’t have all the ingredients? No problem! Here’s how to customize:

  • Swap kielbasa with chicken or turkey sausage for a leaner option.
  • Out of butternut squash? Use cauliflower for low carbs or sweet potatoes if you’re not strict keto.
  • No zucchini? Yellow squash or asparagus works great too.
  • Green bell peppers can stand in for red or yellow if you prefer less sweetness.

Pro Tip
Cut everything to roughly the same size. It’s the secret to even cooking, especially for veggies like squash and zucchini.

How to Make It

How to Make Keto Sheet Pan Sausage and Veggies

Here’s how you pull this dish together—step by step:

  1. Preheat your oven. Set it to 400°F (200°C). Line your baking sheet with parchment paper or foil if you want easier cleanup.
  2. Steam the squash. Place your diced butternut squash in a microwave-safe bowl. Microwave for 2 minutes to soften it slightly so it roasts perfectly.
  3. Prep the rest. While the squash is steaming, slice your zucchini into half-moons (about ½ inch thick), dice bell peppers, and slice your red onion thick for caramelization. Then cut the kielbasa into rounds.
  4. Season everything. Dump the veggies and sausage into a mixing bowl. Drizzle with olive oil, then add thyme, smoked paprika, garlic salt, and black pepper. Toss until every piece is coated.
  5. Spread it out. Arrange everything on the baking sheet in a single layer. If the pan’s crowded, split it between two sheets (this prevents steaming—you want those golden edges!).
  6. Roast to perfection. Bake for 25 minutes. At the halfway mark, give everything a stir for even cooking.
  7. Check for doneness. The veggies should be tender with slightly crisp edges, and the sausage should have that irresistible golden-brown color.

Make It Your Own

Customize Keto Sheet Pan Sausage and Veggies

This recipe is super flexible, so don’t be afraid to get creative:

  • Spice it up. Add a pinch of cayenne or crushed red pepper for heat.
  • Cheesy upgrade. Sprinkle Parmesan on top during the last 5 minutes of roasting.
  • Seasonal swaps. In summer, trade the squash for cherry tomatoes or eggplant. In winter, throw in Brussels sprouts or parsnips.

Feeding different diets? Here’s how to tweak:

  • For gluten-free eaters: Check that your sausage is certified gluten-free (most kielbasas are!).
  • For plant-based folks: Sub the sausage with marinated tofu or plant-based alternatives like Beyond Sausage.

How to Serve & Store It

This dish is versatile when it comes to serving:

  • Keep it simple: Serve as-is for a hearty, complete meal.
  • Add sides: Pair with cauliflower rice or mashed cauliflower for extra volume. Not keto? It’s great with crusty bread or over quinoa too.

Leftovers? No problem. Store them in an airtight container in the fridge for up to 4 days.

  • Reheating Tip: Use a skillet or a 375°F oven for 10 minutes to keep the veggies crisp. Avoid the microwave—it can turn them soggy.
  • Freezing: Portion leftovers into freezer-safe containers for up to 3 months. Thaw overnight in the fridge and reheat as needed.

This isn’t just another sheet pan dinner. It’s a simple, flavorful way to enjoy healthy eating without spending hours in the kitchen. Whether you’re cooking for meal prep, a family dinner, or just yourself, this Keto Sheet Pan Sausage and Veggies recipe is a winner every time.

  • Cook Time: 25 minutes
  • Total Time: 35 minutes
  • Yield: 4 1x
  • Category: Dinner, meal prep, quick keto meals

Ingredients

Scale
  • 14 oz smoked kielbasa sausage, sliced into rounds
  • 1 cup butternut squash, diced
  • bell pepper (yellow, red, or orange), diced
  • 1 small zucchini, sliced into half-moons
  • red onion, thickly sliced
  • 2 tbsp olive oil
  • ½ tsp dried thyme
  • ½ tsp smoked paprika
  • ½ tsp garlic salt
  • ¼ tsp black pepper

Instructions

1. Prep Your Oven and Ingredients

Preheat your oven to 400°F (200°C). Meanwhile, place your diced butternut squash in a microwave-safe bowl with a splash of water. Microwave for 2 minutes—this softens the squash so it roasts perfectly alongside the other veggies.

2. Season Everything

In a big mixing bowl, combine the steamed squash, bell peppers, zucchini, onions, and sausage. Drizzle with olive oil, then sprinkle on the seasonings: thyme, paprika, garlic salt, and black pepper. Toss it all together until everything is well-coated—this is where the magic happens.

3. Spread It Out

Dump the mixture onto a baking sheet (line it with parchment paper for easy cleanup). Make sure everything’s in a single layer, so it roasts instead of steaming. If you’re doubling the recipe, use two pans—it’s worth it for those crispy edges!

4. Roast Like a Pro

Pop the pan in the oven and bake for 25 minutes. At the halfway point (about 12 minutes in), give everything a stir to make sure it cooks evenly and gets those golden, caramelized edges.

5. Time to Serve

Pull the pan out of the oven, take in that incredible aroma, and serve it up! The smoky sausage and tender veggies make for a satisfying, no-fuss meal.

Notes

Tips & Tricks

  • Veggie Cutting 101: Keep your cuts uniform so everything cooks at the same pace. Small diced squash, medium zucchini slices, and thick onion pieces work best.
  • Don’t Crowd the Pan: Overcrowding traps steam, making the veggies soggy. Use an extra pan if needed to keep things crispy and golden.
  • Need a Kick? Add a pinch of cayenne or red pepper flakes if you like a little spice.

Serving Ideas

This dish is fantastic on its own, but you’ve got options:

  • Pair it with cauliflower rice for an extra keto boost.
  • Serve it over quinoa or with crusty bread if some non-keto folks are at the table.
  • Add a simple green salad for a fresh contrast.

Leftovers? No Problem!

This meal stores and reheats like a dream:

  • Fridge: Keep leftovers in an airtight container for up to 4 days.
  • Reheat: Warm them in a skillet or a 375°F oven for 10 minutes to bring back the crisp textures. Skip the microwave if you can—it tends to make the veggies soggy.
  • Freezer-Friendly: Portion leftovers into freezer-safe containers. Freeze for up to 3 months and thaw overnight in the fridge before reheating.
