Baked Italian Polenta and Vegetables

This is what I make when I want something cozy and cheesy, but still want a big serving of vegetables on the plate. The veggies cook down in a skillet first, then get tossed with marinara and basil so every bite tastes like it’s been simmering all day.

Using prepared polenta keeps it fast. You get those creamy cornmeal layers without standing at the stove stirring, and it holds up really well under the saucy vegetables. The final bake is short and hot, just enough to warm everything through and melt the cheese into that bubbly top layer (the best part!).

If you’ve got picky eaters, this is a great one to serve family-style. It looks like a cheesy bake, but it’s packed with eggplant, squash, mushrooms, and spinach. Easy win!

Before You Get Started

Here are a few things worth knowing before you start cooking so everything goes smoothly.

• Time-saving shortcut: Use a tube of polenta and jarred marinara sauce to keep this a true 40-minute dinner.
• Drain the vegetables: Eggplant and mushrooms can release water, so drain any excess liquid before adding marinara so the bake doesn’t turn soupy.
• Veggie swaps: Swap in what you have, but choose vegetables that sauté well and won’t dump tons of water at the end.
• Cut even polenta rounds: Similar thickness helps everything warm through at the same time.

How to Make Baked Italian Polenta and Vegetables

Here’s a quick overview of how to pull this recipe together step-by-step.

1. Sauté The Vegetables

Cook the onion until soft, then add eggplant, zucchini, summer squash, and mushrooms and sauté until tender. Stir in garlic and spinach just until wilted.

• Pro tip: If you see liquid pooling in the pan, drain it off before adding the marinara so the final bake stays thick.

2. Add Marinara And Basil

Stir marinara and chopped basil into the vegetables, then season with salt and pepper so the sauce tastes good on its own.

3. Layer The Bake

Spray a baking dish, layer in the polenta rounds, sprinkle with half the mozzarella, then spoon the veggie marinara over the top and finish with the remaining cheese.

4. Bake Until Bubbly

Bake at 450 degrees until the cheese is melted and the polenta is warmed through, about 12 to 15 minutes. Let it sit for a couple minutes, then scoop and serve!

Recipe Tips and Tricks

Here are the best tips and pro tricks to help this recipe turn out perfectly every time.

• Extra saucy: If you like it extra saucy, add another 1/2 cup marinara before baking.
• Add protein: Stir in vegetarian crumbles, add cooked lentils, or top each serving with a fried egg for an easy protein boost.
• Pesto twist: Stir a spoonful of pesto into the marinara for extra basil flavor and a richer sauce.
• Cheese swaps: Try provolone for a stretchier melt, parmesan cheese for a saltier finish, or a little goat cheese for tang.
• Make it spicier: Add red pepper flakes with the garlic, or drizzle with chili oil right before serving.

Serving Ideas

Here are some easy and delicious ways to serve this recipe.

• Simple salad: Pair with an Easy Arugula Salad to balance the cheesy bake!
• Bread on the side: Serve with a Two Ingredient Dough Breadsticks or Easy Dinner Rolls for dipping into the marinara.
• Protein on the side: Add some Pesto Chicken, Shrimp Piccata, or Parmesan Crusted Pork Chops for extra protein!
• Breakfast-for-dinner: Top a serving with a fried egg and call it a night.
• Leftover upgrade: Spoon leftovers into a bowl and add extra basil and parmesan to freshen it up.

Storage & Reheating

Here’s how to store, reheat, and enjoy your leftovers.

• Storage: Cool completely, then refrigerate in an airtight container for up to 4 days.
• Freezer: Freeze in portions for up to 3 months. Thaw overnight in the fridge for the best texture.
• Reheating: Reheat in the oven or toaster oven until hot and the cheese softens again, or microwave in short bursts.
• Leftovers: Chop and reheat in a skillet with a splash of marinara, or turn it into a quick lunch bowl with extra spinach stirred in.
