How to Make One Pan Sausage and Veggies with Lemon Aioli Recipe
Step 1: Prepare Your Oven and Baking Sheet
Get started by preheating your oven to 400 degrees F. Line a large baking sheet with foil for easy cleanup, which means less time scrubbing and more time enjoying your meal. A simple step that makes your cooking experience much more enjoyable.
Step 2: Get the Vegetables Ready
Trim your Brussels sprouts by removing any yellow leaves and halving the larger ones so they roast evenly. Chop your sweet potato into hearty chunks that will crisp up on the edges but stay tender inside. Slice the colorful bell peppers and chop the red onion into rustic chunks that caramelize beautifully in the oven. Smash but don’t mince your garlic cloves to release their fragrance without burning during roasting.
Step 3: Combine Everything on the Pan
Spread out the Brussels sprouts, sweet potato, bell peppers, red onion, and whole garlic cloves onto the baking sheet. Nestle the bratwurst sausages right on top of the veggies for that perfect mingling of flavors as everything cooks together. This simple assembly is the heart of the One Pan Sausage and Veggies with Lemon Aioli Recipe, making cleanup a breeze while layering flavors beautifully.
Step 4: Season and Oil
Drizzle 1/4 cup of olive oil over everything, then sprinkle the onion soup mix evenly on top. Use your hands to gently toss and coat the veggies and sausages with the oil and seasoning, adding a little extra olive oil if needed to ensure everything looks nicely moistened. This step is key to that irresistible roasted flavor and texture.
Step 5: Arrange and Roast
Try to spread the veggies out in a single layer with some space between them — it helps them caramelize instead of steam. Put the sausages on top, then pop the pan into your preheated oven. Roast for 30 minutes, flipping the sausages halfway through if you want an extra crispy crust all around.
Step 6: Whip Up the Lemon Aioli
While the veggies and sausages are roasting, whip together your lemon aioli. In a small bowl, mix 1 cup of mayonnaise, 3 tablespoons lemon juice, 3/4 teaspoon kosher salt, and 1 to 2 cloves of smashed and minced garlic. Add cracked pepper to taste — this bright, creamy sauce is the perfect tangy counterpoint to the rich roasted flavors.
How to Serve One Pan Sausage and Veggies with Lemon Aioli Recipe

Garnishes
Fresh parsley sprinkled on top adds a pop of green and a fresh, herbaceous aroma that brightens the entire dish. It’s a small detail that makes a big difference when serving.
Side Dishes
This dish pairs wonderfully with hot rice or buttered noodles to catch all those delicious juices. If you want to make it even more comforting, try topping it with a fried or poached egg — runny yolk heaven!
Creative Ways to Present
For a fun twist, serve the roasted veggies and sausage over a bed of creamy polenta or alongside warm, crusty bread to scoop up the luscious lemon aioli. You could also turn this into a picnic-friendly meal by packing the components separately and assembling on the spot for fresh, vibrant bites wherever you are.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making for an even tastier lunch or dinner the next day.
Freezing
You can freeze the roasted sausage and veggies in a freezer-safe container for up to 2 months. For best texture, freeze the lemon aioli separately as it may change consistency when frozen. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat your leftovers gently in a skillet or the oven at 350 degrees F until warmed through to keep the veggies from getting mushy. Warm your aioli separately and serve alongside for that fresh, zesty touch.
FAQs
Can I use other types of sausages for this recipe?
Absolutely! Bratwurst works beautifully, but Italian sausage, kielbasa, or even chicken sausage will all bring delightful flavors. Just keep an eye on cooking times as they might vary slightly.
Is this recipe suitable for meal prep?
Yes, it’s perfect for meal prep thanks to its one-pan simplicity and delicious leftovers. Just store and reheat as needed for quick, wholesome meals throughout the week.
Can I make the lemon aioli dairy-free?
Definitely. Since traditional mayo-based aioli is naturally dairy-free, just check your mayonnaise ingredients or use a vegan mayo to accommodate dairy-free or vegan diets.
What if I don’t have onion soup mix on hand?
You can easily substitute with a blend of dried onion powder, garlic powder, salt, pepper, and a bit of dried herbs like thyme or parsley to mimic that savory seasoning.
Can I add other vegetables to this dish?
For sure! This recipe is versatile. Try adding carrots, zucchini, or even parsnips for different flavor and texture variations. Just adjust the cutting size so everything cooks evenly.
