- Crispy Polenta Slices (Air-Fried)
If you're looking for a quick and satisfying side dish or snack, these Crispy Polenta Slices made in the air fryer are a total game-changer. At first glance, tubed polenta doesn't look like much, but it's a hidden gem in my kitchen.
The great thing is that you can find pre-cooked polenta rounds from most grocery stores. This polenta recipe is versatile, crunchy, and absolutely delicious.
I sliced mine about ½ inch thick and lightly brushed each slice with olive oil before placing them on a baking sheet or right into the air fryer basket. In just a few minutes, they turn perfectly golden brown and crispy on the outside, while staying creamy on the inside.
You could also pan fry or even oven bake the polenta slices, but I find that using the air fryer saves time and cleanup-plus, you only need a couple of tablespoons olive oil.
Once they're crisped up, I love sprinkling grated Parmigiano Reggiano over the hot slices for an added savory kick. They make an amazing addition to salads, antipasto platters, or served as a base for sautéed veggies or a poached egg cooked over medium.
After you try this easy recipe, I guarantee you'll be dreaming of different ways to cook them up!

🍽️ How to cook polenta slice?
Here is how to make these easy polenta cakes (the full recipe is below!):
Gather up your ingredients.
The first thing I did was cook up the quick fresh canned cherry tomato sauce to go with it. This is optional. You could use a very good ready-made sauce to make it quicker!
Step 1: Preheat air fryer to 400°F. Cut the polenta into ½" thick slices. Here's the ingredients ready to assemble the polenta slices.
Step 2: Spray or brush each side of the polenta cakes with the 1 tablespoon olive oil.
Step 3: Season with salt and pepper.
Step 4: Spray the tray (or basket) with non-stick cooking spray.
Step 5: Add the polenta slices to the tray spacing them out.
Step 6: Cook the polenta cakes for 25-30 minutes, flipping halfway through cooking, until edges are golden brown.
Step 7: Top with grated Parmigiano and return to the air-fryer for a couple minutes, or until melted.
Step 8: Serve with my tomato sauce or any dipping sauce you like!
How to bake polenta slices in the oven?
No air-fryer, no problem! Here is how to cook it up in your oven:
- Heat the oven to to 400°F.
- If you have a wire rack, place it on top of a baking sheet. Line with parchment paper. Spray the wire rack with cooking spray, and add the polenta slices in a single layer.
- If you have a wire rack, place it on top of a baking sheet. Line with parchment paper. Spray the wire rack with cooking spray, and add the polenta slices in a single layer.
- If you do not have a wire rack, line the baking sheet with parchment paper and heat the baking sheet while the oven heats up. Spray the baking sheet and carefully add the polenta slices (take care to not burn your fingers as it will be a hot pan).
- Bake in 400°F oven for 15-20 minutes, or until nicely crisped and has a nice color.
- If adding cheese, sprinkle on the Parmigiano the last couple of minutes.
What to serve with sliced polenta?
These polenta rounds go really nicely with any roasted vegetable, or side dish. Here are some other ideas for you!
- Lentil Soup >>> One of my favorite soups! Cooks up fast and is so flavorful!
- Insalata mista >>> A really great quick and simple Italian salad.
- Panzanella Toscana >>> This is a tasty Tuscan salad! It's so easy to make and also very flavorful.
- Meatballs >>> Super delicious meatballs that are great with polenta!

🫙 Leftover and Storing ....
- Refrigerate: Store any leftovers in the fridge in an airtight container and air fry or pan fry to reheat-just a few minutes on each side to bring them back to life.
- Freeze: I do not recommend freezing any leftovers.
📃 Substitutions & Variations for crispy polenta
- Make polenta chips - This quick appetizer is a great recipe for changing up the shape and thickness of the polenta. You can easily make perfect round chips that are a tad bit thinner. They go great with salsa, dips, or even with a soup.This is why buying a polenta tube makes for a great snack - because you have tons of options! You will have to adjust cooking times for each variation.
- Add seasonings - You could keep it simple with a little sea salt and pepper, and you can also add other flavors. Truffle salt would be delicious, as would chili powder. You can even use different herbs on it if you're wanting to give it more flavor.
- Polenta fries - You can easily make fries by cutting the polenta into ½" thick sticks instead of discs. Just cook as directed for crispy fries and serve with your favorite dips.
- Dairy-free- If you're vegan, or dairy-free, you could use your favorite dairy-free (vegan)cheese to sprinkle on top.
☑️ Expert tips for polenta in a tube recipes:
- Slice it evenly: For consistent cooking, cut your polenta rounds into even ½-inch thick slices. This ensures they cook evenly whether you're using an air fryer, oven, or pan fry method.
- Yield: You should get 12 slices if you cut them evenly, on an 18-ounce roll.
- Pat the slices dry: Tube polenta can sometimes be a bit moist straight out of the package. Pat each slice with a paper towel before cooking to help them crisp up better, especially if you're air-frying or baking.
- Use a bit of oil for crispiness: Brush both sides lightly with olive oil (about 1-2 tablespoons olive oil) to help them turn golden brown and crispy. Very important to not skip this step.
- Preheat your air fryer or oven: Make sure your fryer or oven is preheated before adding the polenta slices. This gives them that immediate heat boost for a better texture and color.
- Don't overcrowd the pan or fryer: Give the slices room to breathe! Spread them out on the baking sheet or in the air fryer basket to ensure even cooking and avoid soggy spots.
- Try different seasonings: You could use grated Parmigiano, garlic powder, or Italian herbs, you can switch it up with smoked paprika, chili flakes, or chopped fresh rosemary for variety.
- Use as a base for toppings: Crispy polenta rounds make a great base for things like sautéed mushrooms, marinara sauce, poached eggs, or even a quick veggie stir-fry. Think of them as mini edible plates!
FAQ's
Yes, it does crisp up on the outside. Brush the outside of the polenta slices with oil (or even melted butter) to help the exterior crisp up. The inside will stay soft
The longer you cook it in the air fryer, the crispier even the inside will get, which will turn it into a polenta chip.
Tubed polenta has a mild corn flavor. When it is sliced and heated up, it goes well with so many different things.
Polenta tubes are already pre-cooked, and need to be sliced and heated. You could heat it by grilling, roasting, broiling, or sauteing. The slices will get a nice color on the outside, and then could be topped with different sauces, vegetables, proteins, or cheeses.
Cornmeal and polenta are practically the same product, except for the grain consistency. Cornmeal is softer and mushier, and polenta more coarsely ground, and has more of a bite.
Yes, tubed polenta is pre-cooked, which saves on time when making certain recipes.
The tubed polenta brands I've always bought are shelf-stable and can be found in the dry pasta aisle or even in the produce section. Sometimes I've found it refrigerated where they have meat alternatives.
In order to get the polenta crispy and evenly cooked, you will need to not overcrowd it in the air-fryer. Spread it out so it will crisp up nicely.
Polenta tubes are now at every market I visit. You need to ask someone that works in the market where it is if you can't find it. Sometimes it's in the produce section, sometimes in the pasta section.
I made a super quick homemade tomato sauce. You could use your favorite jarred sauce. Or choose a favorite dipping sauce.
You could spray your basket with cooking oil or you could line it with parchment paper. There is even a special precut air-fryer sized parchment paper for a round or square air fryer. There is one with ventilation holes and one without.

📖 Recipe
Crispy Polenta Slices (Air-Fried)
Equipment
Ingredients
- 18 oz tube precooked polenta
- 1 tablespoon extra-virgin olive oil
- 1 teaspoon sea salt
- ¼ teaspoon black pepper or more to taste
- 2 tablespoon grated Parmigiano-Reggiano cheese
- ¼ cup of thin slices of Parmigiano-Reggiano cheese
- Favorite dipping sauce like marinara sauce
Instructions
Prep sauce:
- If you're planning to serve these with sauce-and I highly recommend it-go ahead and make a homemade sauce before prepping the polenta. Of course, a really good store-bought marinara will work beautifully too and save you some time!
Preheat the air-fryer:
- Start by preheating your air fryer to 400°F, following the manufacturer's instructions.
Slice and prep the polenta:
- Next, grab your tube of polenta. Carefully slice off one end, then gently squeeze it out onto a cutting board. Pat the polenta dry with a paper towel to help it crisp up nicely. Using a sharp knife, cut into ½-inch thick rounds.
- Brush or spray both sides of each polenta slice with about 1 tablespoon of olive oil, and season with a little sea salt and black pepper to taste.
Prep air-fryer:
- Once your air fryer is ready, spray the basket or tray with nonstick spray to prevent sticking. Arrange the polenta rounds in a single layer, making sure there's space between each one so they get nice and crispy.
Cook in the air-fryer:
- Air fry at 400°F for 25-30 minutes, flipping the slices halfway through, until the edges are beautifully golden brown.
Add on some cheese:
- Sprinkle about 2 tablespoons of grated Parmigiano cheese over the tops of the slices and pop them back in the air fryer for 1-2 minutes, just until the cheese is melted and a little toasty.
Serve with sauce:
- Top with extra Parmigiano-Reggiano or fresh chopped Italian parsley, if you'd like. Serve warm with your favorite sauce for dipping

Notes

These crispy polenta slices, that too airfryed are so delicious and easy to put together. I made it for our dinner. so good.
What a great idea, we love polenta. My family loved these, made my own polenta as you can't buy tube polenta in the UK. Loved the touch of grilled parmesan, delicious.
I love polenta and I love crispy polenta even more! This is such a great idea for an appetizer...I'm definitely serving this at my next party.
So good!! Added extra grated cheese at the end instead of slices.
I was looking for a different way to eat tube polenta and never thought to pop them in my air fryer! GREAT idea! So easy and tasty! I cheated and used a jar sauce, but I do want to try out your sauce!
