Baked Polenta Recipe With Mushrooms & Spinach: A Quick & Easy 30-Minute Dinner

Polenta – an Italian version of southern grits, made from coarse cornmeal and cooked up like porridge – makes the perfect complement to vegetables and/or meat. It can also be substituted for pasta for a gluten-free base. Polenta's mild, corn flavor goes with sweet and savory. You can cook your own, or you can opt for the pre-cooked roll available in the pasta aisle of the grocery store.

This polenta recipe with mushrooms and spinach uses the roll polenta. And as usually, I've added a lot of vegetables to this recipe! Because I had some rotisserie chicken that needed to be used, I added that in, but leave it out if you want a vegan dinner. Serve this easy polenta recipe for dinner or lunch with a fresh salad

Cuisine: Italian 
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes
Servings: 2


  • 1 tube (18 ounces) polenta, cut into 1/2-inch slices
  • garlic powder and onion powder, to taste
  • 2 tablespoons olive oil (divided)
  • 1 onion, sliced
  • 8 ounces mushrooms, sliced
  • 2 cloves garlic, minced
  • 8 ounces rotisserie chicken, diced (omit for vegan)
  • 2 tablespoons soy sauce
  • 1 package (5 ounces) fresh baby spinach leaves
  • splash of lime juice (optional)

Here’s how to make it:

  1. Grease a shallow baking pan with oil or cooking spray.  Arrange slices of polenta on pan and brush on additional oil. Sprinkle with garlic powder and onion powder. Bake in a preheated 450-degree F oven for 20 minutes, flipping halfway through.
  2. Heat a tablespoon of oil in large skillet over medium-high heat. Add mushrooms and onions and sauté for 3 to 4 minutes or until beginning to brown. Add minced garlic and cook for an additional 30 seconds. Add chicken and cook until warm. Add soy sauce and spinach and cook for 1 to 2 minutes, or until spinach is wilted. Add lime juice. Serve mushroom mixture over polenta.

I enjoy polenta because it takes on the flavors of whatever you're serving it with (and it's gluten-free, bonus for me). I can't wait to try this recipe!
Making this recipe but without the meat so it’s vegetarian. Yummy.
I always forget about polenta. So good!
