Chicken Sausage & Veggie Sheet Pan Dinner

Chicken Sausage & Veggie Sheet Pan Dinner

This Chicken Sausage & Veggie Sheet Pan Dinner is one of those meals where everything cooks together, the flavors just work, and the cleanup is minimal. It’s simple, flexible, and perfect for a busy weeknight when you don’t feel like overthinking it.

I made this using a mix of potatoes, zucchini, mushrooms, onions, and tomatoes, along with Italian-style chicken sausage, and it turned out so good. The roasted tomatoes with the Italian seasoning really stood out—they get soft and slightly caramelized and add so much flavor to the whole dish.

A few things that made this recipe really work

First, giving the potatoes a head start is key. They need a little extra time in the oven to get tender and develop those golden edges, so roasting them first makes a big difference in the final texture.

Second, don’t overcrowd the pan. I split everything between two sheet pans so the vegetables could actually roast instead of steaming. This is one of those small things that makes a big difference.

I used my go-to sheet pans with silicone liners for this, and it made cleanup so easy.

My favorite shortcut for this recipe

I used a gallon-sized zip-top bag with a bag holder to season everything, and I’m not kidding—it makes this so much easier.

I started with the potatoes in the bag, added olive oil and seasoning, shook everything up, and poured them onto the sheet pans. Then I used the same bag for the rest of the vegetables. No extra dishes, no mess, and everything gets evenly coated.If you don’t have a bag holder, I’ll link the one I use—it’s one of those little things that makes cooking faster and less frustrating.

Let’s talk about the zucchini (so you can learn from my mistakes)

I added my zucchini in at the same time as the rest of the vegetables, and while it still tasted good, it ended up a little softer than I would’ve liked.

Next time, I would wait and add the zucchini during the last 15ish minutes of cooking. That way it stays tender but not mushy and holds its shape better.

Everything else came together exactly how I wanted it to.

How to Make Chicken Sausage & Veggies Sheet Pan Dinner (Step-by-Step)

*printable recipe card is available at the bottom of this page

Step One: Prep the potatoes

Wash and dice the potatoes into bite-sized pieces.

Add them to a large zip-top bag with 3 tablespoons of olive oil and about half of the seasoning blend. Seal the bag and shake until everything is evenly coated.

👉 This is where I use my bag holder—it keeps everything upright and makes this so much easier.

Step Two: Roast the potatoes

Spread the potatoes evenly across two sheet pans lined with silicone liners or parchment paper.

Bake at 425°F for 15 minutes to give them a head start.

👉 Don’t skip this step—this is how you get tender potatoes with those golden edges.

Step Three: Prep the remaining ingredients

• Slice the chicken sausage into rounds
• Slice the zucchini
• Slice the mushrooms
• Slice the onion

Step Four: Season the veggies and sausage

Using the same zip-top bag (no need to dirty another one), add the mushrooms, onion, and tomatoes.

Pour in the remaining olive oil and seasoning. Seal and shake to coat.

👉 Reusing the same bag keeps this super simple and cuts down on waste and cleanup.

Step Five: Add everything to the sheet pans

Remove the potatoes from the oven.

Add the seasoned vegetables and sliced chicken sausage to the sheet pans and gently toss everything together.

Step Six: Roast until tender

Return the pans to the oven and bake for 25–30 minutes, stirring halfway through, until everything is cooked through and lightly browned.

👉 Zucchini tip:
I added mine at this stage, but next time I would wait and add it during the last 10–15 minutes so it doesn’t get too soft. If you didn’t add them to the bag earlier, add them now.  Shake the bag so the zucchini gets coated with the oil and seasoning that’s still in the bag.

Step Seven: Add the cheese

Sprinkle the mozzarella evenly over the top and place under the broiler for 2–3 minutes, until melted and slightly golden.

Step Eight: Serve and enjoy

Serve warm and enjoy the rest of your evening.

Why this is a go-to dinner

• It’s a full meal on one sheet pan (protein, veggies, and carbs)
• You can swap in whatever vegetables you have
• Minimal prep and easy cleanup
• Great for busy nights when you just need something that works

And that melty mozzarella on top at the end? It pulls everything together and makes it feel a little more comforting and complete.
