I can’t tell you how much we love this recipe. It’s easy to pull together and it’s truly delicious. We especially enjoy the sliced polenta. It’s a nice change from roasted potatoes or pasta with spaghetti sauce.

I’m a huge polenta fan (I could eat a whole potful of my Instant Pot polenta) so I really appreciate the shelf-stable prepared polenta. It’s all ready to eat and keeps in your pantry for up to three months. Just remove the wrapping, slice it into rounds, and heat it. You can jazz it up any number of ways. (Try it with sautéed spinach and a fried egg for a quick breakfast or lunch.)

And for those of you who are gluten-intolerant, polenta is naturally gluten-free since it’s made from cornmeal (as always though, check your labels to be sure).

Sheet Pan Info

Not sure what a sheet pan is? It’s simply a large rimmed baking pan. We typically use the half sheet pan size, about 13 x 18 inches. There are several different types: aluminum, non-stick, textured or smooth.

Why You’ll Love This Sheet Pan Dinner

  • Convenient weeknight dinner idea: A sheet pan Italian sausage dinner is often what I fall back on for weeknights. Sheet pan dinners are like a safety net so we don’t resort to take-out. A package of Italian sausages in your fridge or freezer means you’ll always be able to throw a quick dinner together.
  • Easy to make (and clean up): You can have dinner in the oven in less than 15 minutes! Take the sausages out of the fridge (or straight from the freezer), throw them on a sheet pan with polenta and veggies, and pop it all into the oven. Easy and delicious! And there’s only one pan to wash after dinner.
  • Versatile: There are many ways to make this Italian sausage sheet pan dinner your own, depending on your preferences and what you happen to have in your pantry and refrigerator. Check out the Make It Your Own section below for suggestions.
  • Healthy: This dinner includes a healthy serving of broccoli, a cruciferous vegetable which has loads of antioxidants and fiber. Tomato-rich marinara has health benefits and polenta is surprisingly good for you, too (yay!); it’s a complex carb with protein and fiber.

What You’ll Need

  • Italian Sausages: Choose your preferred type of sausage: pork, turkey, or chicken. Both sweet (mild) or hot (with red pepper flakes) sausages are fine, depending on what you like best. Turkey sausage is lower in saturated fat and calories.
  • Pre-Cooked Polenta: Usually sold in tubes, pre-cooked polenta is shelf-stable and does not need to be refrigerated. Since it’s made from ground corn (cornmeal), it is gluten-free. Simply remove it from the packaging and slice it into rounds. Refrigerate any polenta you don’t use right away.
  • Broccoli: Look for a firm, dark green head of broccoli (or three crowns of broccoli). Don’t discard the large stem. Simply remove the tough peeling from the stem and slice it into bite-sized pieces to be added to the sheet pan.
  • Red Onion: You’ll need half of a large red onion, or another type of sweet onion. Avoid yellow cooking onions for roasting; they tend to get a bit tough.
  • Olive Oil: A light coating of oil is essential for browning and crisping. Olive oil is a flavorful heart-healthy oil but other types of oil can be substituted.
  • Dried Oregano: A common pantry item, dried oregano goes well with the Italian sausage. If you prefer, fresh oregano can be substituted. Dried Italian seasoning is another option.
  • Garlic Powder, Kosher Salt, Coarsely Ground Black Pepper: These simple seasonings add so much flavor. Be sure to use garlic powder, not garlic salt.
  • Marinara or Pizza Sauce: Choose your favorite brand or make your own. Try my easy homemade pizza sauce recipe. You’ll love the fresh taste.

How To Prep Broccoli For Roasting

Cut the head of broccoli evenly into bite-sized pieces. If you plan on using the thick stem, peel it and slice it into rounds. Rinse the broccoli thoroughly with cool water. Dry the broccoli as much as possible. I usually give it a spin in my salad spinner. Why? If the broccoli is dripping wet, the oil won’t adhere and the broccoli will steam instead of roast.

How to make This Sheet Pan Dinner

Ready to get started? Turn your oven on and start preheating it. Prepare the pan by giving it a good coating of olive oil.

Prep the polenta. Slice the polenta into 8 even slices about a half inch thick. Place the slices in the sheet pan and flip them over once so both sides have a thin layer of oil. Sprinkle the slices with a pinch of dried oregano.

Arrange the Italian sausages in the pan. The arrangement is up to you. You can scatter the sausages among the polenta or segregate each ingredient (like the photos).

Add the veggies. In a large bowl, toss the broccoli florets and onions with a couple tablespoons of oil, garlic powder, salt and pepper. If you don’t like your broccoli as well done or your sausages are frozen, let the sausage and polenta roast for 15 to 20 minutes before adding the broccoli to the pan.

Bake. Pop the sheet pan into the oven for 20 minutes. Remove the pan from the oven after 20 minutes; flip the sausages and give the veggies a stir. If you want, flip the polenta slices, too. Put the pan back into the oven for about 10 minutes or until the sausages are cooked through. (If they were frozen, they’ll take a little longer to cook.)

Serve. Place one sausage, two slices of polenta, and a scoop of vegetables on each plate. Garnish with a side of marinara or drizzle it on top. Enjoy!

Dessert ideas: If you have room for dessert, homemade vanilla pudding or chocolate pudding is a great finale, especially topped with a big spoonful of whipped cream. Polenta and pudding, does it get any better?

Tips For Success

  • Choose the right pan. If you use a pan that’s too small or with higher sides, there won’t be good air circulation. Instead of browning nicely, the contents will steam, take longer to cook, and become somewhat soggy.
  • Preheat the oven. It’s important that your oven is piping hot before you put the loaded sheet pan in. Turn the oven on to 425ºF before you start prepping the food.
  • Slice and dice uniformly. Being consistent with your cutting means that the food will cook evenly. Tiny pieces cook more quickly and may burn; large pieces take longer and may not get cooked through.

Make It Your Own

  • Add seasonings of your choice. I kept things pretty simple with garlic powder, dried oregano, salt and pepper. It’s easy to personalize this recipe with additional or different seasoning. Try my all-purpose seasoning, Italian seasoning, or herbes de Provence.
  • Use a different kind of sausage. Any uncooked sausage links will work in this recipe: garlicky kielbasa, bratwurst, or chicken sausage. If you have smoked or cooked sausages, be sure to check out my sausage sheet pan dinner.
  • Substitute another vegetable. Not a fan of broccoli? Try Brussels sprouts, cauliflower, zucchini, or carrots instead. Add a package of mushrooms or a bell pepper, cut into chunks. A combination of veggies is delicious.
  • Make it without polenta. If you’re looking for a simpler recipe with just sausage, bell peppers, and onions, be sure to check out my baked Italian sausage.

Make Ahead Ideas

This meal is easy to prep. If you want to get a head start, cut and wash the broccoli and red onion in the morning or even the night before. Refrigerate the cut vegetables in a covered container or resealable bag until you’re ready to use them.

Storage & Reheating Tips

If you happen to have leftovers, refrigerate them for up to 3 days, or freeze in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.

For best results, use your air fryer or toaster oven to reheat the leftovers. Cutting the sausage into slices will help it reheat more quickly and evenly.
