Can I make the polenta ahead?

Yes. Cook and chill the polenta up to 2 days ahead, then cut and pan-fry the cakes when ready to serve.

Why are my polenta cakes falling apart?

The polenta may not be firm enough. Chill it longer and use a thin spatula to flip once the first side is deeply golden.

Can I roast different vegetables?

Yes. Use vegetables that roast in similar-size pieces so they finish together.

Is cornmeal always gluten-free?

Corn is naturally gluten-free, but cornmeal can have cross-contact, so choose certified gluten-free polenta when needed.

Instructions

Preheat your oven to 425 degrees F. Line a baking sheet with parchment paper or a silicone mat.
In a medium saucepan, bring 4 cups of water to a boil. Add 1/2 teaspoon of salt.
Slowly whisk in the cornmeal to avoid lumps. Reduce heat to low and cook, whisking frequently, until the mixture thickens and polenta pulls away from the sides, about 15-20 minutes.
Remove the polenta from heat. Stir in the lemon zest, lemon juice, chopped parsley, thyme, 2 tablespoons olive oil, garlic powder, remaining salt, and black pepper.
Spread the polenta evenly into a greased or parchment-lined 9x9 inch pan. Smooth the surface with a spatula. Let cool at room temperature for 30 minutes, or until firm. For quicker cooling, place in the refrigerator for 20 minutes.
Meanwhile, toss zucchini, bell pepper, eggplant, red onion, and cherry tomatoes with 2 tablespoons olive oil, balsamic vinegar, dried oregano, salt, and pepper on the prepared baking sheet.
Roast the vegetables in the preheated oven for 20-25 minutes, turning halfway through, until tender and caramelized.
Once polenta is firm, turn it out onto a cutting board and cut into 8 equal square or round cakes.
Heat a non-stick skillet over medium heat and add a little olive oil. Fry the polenta cakes for 3-4 minutes per side until golden and crispy.
Serve the warm polenta cakes topped or accompanied by the roasted vegetables. Garnish with extra parsley and lemon wedges if desired.

Tips

Allergen Overlap Note

Choose certified gluten-free polenta or cornmeal, especially if cooking for someone with celiac disease. Use a clean skillet and spatula, since crumbs from regular breaded foods can cling to cookware.

Texture Expectations

The polenta needs to cool until firm before cutting, or the cakes may break in the skillet. Expect crisp golden edges with a creamy center and juicy roasted vegetables on the side.

Dining With Non-GF Family Note

Serve the polenta cakes and vegetables as the gluten-free base, then let others add cheese or non-gluten-free sides separately. Use a dedicated serving spatula for the gluten-free cakes.

Frequently Asked Questions

Can I make the polenta ahead?: Yes. Cook and chill the polenta up to 2 days ahead, then cut and pan-fry the cakes when ready to serve.
Why are my polenta cakes falling apart?: The polenta may not be firm enough. Chill it longer and use a thin spatula to flip once the first side is deeply golden.
Can I roast different vegetables?: Yes. Use vegetables that roast in similar-size pieces so they finish together.
Is cornmeal always gluten-free?: Corn is naturally gluten-free, but cornmeal can have cross-contact, so choose certified gluten-free polenta when needed.

Ingredient Replacements

Gluten-free polenta: Use certified gluten-free yellow cornmeal or quick-cooking polenta. Avoid bulk-bin cornmeal if cross-contact is a concern.
Fresh herbs: Use basil, rosemary, or chives if parsley and thyme are unavailable. Dried herbs work too, but use smaller amounts.
Vegetables: Swap zucchini, bell pepper, eggplant, onion, or tomatoes with mushrooms, asparagus, carrots, or summer squash.
Balsamic vinegar: Use red wine vinegar or lemon juice for a brighter finish. Check flavored vinegars for gluten-containing additives.
Pan-frying oil: Use olive oil or avocado oil and keep the skillet hot enough to crisp the cakes without soaking them.

Storage and Reheating

Store polenta cakes and roasted vegetables separately in airtight containers for up to 4 days. Reheat cakes in a skillet or oven to restore crisp edges, and warm vegetables separately so they do not soften the cakes.
