Ingredients for Sheet Pan Polenta with Mushrooms
Okay, let’s raid the fridge and pantry! Here’s what you’ll need for this ridiculously easy dish (and yes, I’m particular about some of these – it makes all the difference):
- 1 tube (18 oz) pre-cooked polenta – sliced into ½-inch rounds (look for the plain kind near the pasta or in the specialty foods aisle)
- 8 oz cremini mushrooms – sliced (I like these for their earthy flavor, but use what you’ve got)
- 2 tbsp good olive oil – the nice stuff you’d drizzle on bread, not the mystery bottle in the back of your cabinet
- 2 cloves garlic – minced (fresh only, please – that jarred stuff won’t do it justice)
- 1 tsp dried thyme – rub it between your fingers before adding to wake up the flavor
- ¼ cup grated Parmesan – optional but highly recommended for that salty punch
- Fresh parsley – for that pretty green finish
See? Nothing crazy – just simple ingredients that turn into something magical in the oven. Now let’s make some kitchen magic!
Equipment You’ll Need
Grab these basics from your kitchen – no fancy gadgets required:
- A trusty sheet pan (half-sheet size works perfectly)
- Parchment paper – saves cleanup time and prevents sticking
- Your favorite chef’s knife for slicing
- A small mixing bowl (or just use the sheet pan itself to toss everything!)
How to Make Sheet Pan Polenta with Mushrooms
Alright, let’s get cooking! This is so easy, you’ll wonder why you haven’t made it every week. Follow these simple steps, and you’ll have a delicious meal in no time.
Step 1: Preheat and Prepare
First things first – preheat your oven to 425°F (220°C). While it’s heating up, line your sheet pan with parchment paper. Trust me, this little step saves you from scrubbing later!
Step 2: Arrange and Season
Now, grab your polenta slices and mushrooms. Arrange them in a single layer on the sheet pan – don’t overcrowd! Drizzle with olive oil, then sprinkle with salt, pepper, thyme, and that minced garlic. Toss everything gently to coat evenly. Your kitchen should already smell amazing.

Step 3: Bake to Perfection
Pop that pan in the oven and bake for 20-25 minutes. You’re looking for crispy, golden edges on the polenta and tender, juicy mushrooms. If you want extra crispiness, turn on the broiler for the last 2-3 minutes, but keep an eye on it – it can go from golden to burnt in a flash! For more tips on achieving the perfect crisp, check out Serious Eats’ guide to roasting vegetables.
Step 4: Garnish and Serve
Once it’s out of the oven, sprinkle with Parmesan cheese (if you’re using it) and a handful of fresh parsley for that pop of color. Serve it straight from the pan – no need to be fancy. Pair it with a simple salad or some crusty bread, and you’ve got yourself a meal that’s as easy as it is delicious.
Tips for the Best Sheet Pan Polenta with Mushrooms
Want to make this dish even better? Here are my tried-and-true tips:
- Slice evenly: Cut your polenta into ½-inch rounds for consistent cooking – no one wants half-raw, half-burnt polenta!
- Don’t crowd the pan: Give your polenta and mushrooms room to breathe. Overcrowding = steaming, and we want crispy, not soggy.
- Check early: Ovens vary, so start checking at 20 minutes. The polenta should be golden, and the mushrooms tender.
- Oil matters: Use good olive oil for flavor – it’s worth it!
Follow these, and you’ll have a dish that’s restaurant-worthy every time.
Variations for Sheet Pan Polenta with Mushrooms
One of the best things about this recipe? You can tweak it endlessly based on what’s in your fridge or your mood! Here are some of my favorite twists:
- Mushroom mix-up: Swap creminis for shiitakes, portobellos, or even wild mushrooms when you’re feeling fancy. Learn more about different types of mushrooms.
- Veggie boost: Toss in some cherry tomatoes, bell peppers, or zucchini for extra color and nutrients.
- Vegan version: Skip the Parmesan or use nutritional yeast for that cheesy flavor.
- Spice lover’s dream: Add a pinch of red pepper flakes or smoked paprika for heat.
See? Endless possibilities from one simple recipe base!
Serving Suggestions
This sheet pan polenta is practically begging to be paired with something fresh and crunchy! My go-to? A simple arugula salad with lemon vinaigrette – the peppery greens cut through the richness perfectly. For heartier appetites, add some crusty bread to soak up those delicious mushroom juices. Roasted asparagus or Brussels sprouts make fabulous veggie sides too – just pop them in the oven while the polenta bakes!
Storage and Reheating
Got leftovers? Lucky you! Store them in an airtight container in the fridge for up to 3 days. When reheating, skip the microwave – unless you love soggy polenta (yuck). Instead, pop it back in a 350°F oven for 10 minutes or crisp it up in a dry skillet over medium heat. That way, you’ll keep all that wonderful texture we worked so hard for!

FAQ
Got questions? I’ve got answers! Here are the ones I get asked most about this sheet pan wonder:
Can I use homemade polenta instead of pre-cooked?
Absolutely! Just spread your freshly cooked polenta on a baking sheet, chill until firm, then slice into rounds. You’ll need about 2 cups of cooked polenta to match the tube.
How do I prevent sticking without parchment paper?
Give your sheet pan a good coating of oil or nonstick spray. A little extra olive oil on the polenta slices helps too – crispy edges guaranteed!
Can I freeze leftovers?
Honestly? The texture suffers. Polenta gets grainy when frozen. But it keeps beautifully in the fridge for 3 days – just reheat as needed!
What if my mushrooms release too much liquid?
No worries! Just pat them dry before arranging on the pan. And remember – single layer is key for proper roasting, not steaming!
