Polenta isn’t usually the first thing that comes to mind for a comforting, crowd-pleasing dinner, but this tomato basil polenta bake with bubbling mozzarella is here to change that. It’s a simple dish that pulls together creamy, fragrant polenta with fresh basil, sweet cherry tomatoes, and plenty of melty cheese. Whether you’re cooking for a busy weeknight or want a cozy vegetarian meal to share, this bake comes together quickly and never disappoints. The pie-like texture makes it easy to slice, so it’s perfect for serving at the table or packing for lunch the next day. The trick to success here is letting the polenta cool just enough before folding in the egg and cheese, which keeps it creamy but sliceable after baking. Pressing the tomatoes into the surface before topping with mozzarella also helps the flavors to meld and gives a nice fresh pop with each bite.

Ingredients
- 1 cup (170 g) quick-cooking polenta
- 4 cups (960 ml) vegetable or chicken broth
- 1 large egg
- 1 cup (150 g) cherry tomatoes, halved
- 1 cup (115 g) shredded mozzarella cheese

- 2 tablespoons (8 g) chopped fresh basil
- Freshly ground black pepper, to taste
Ingredient Notes
Choosing quick-cooking polenta saves time without losing that creamy texture. Using broth instead of water adds a layer of flavor—vegetable broth keeps it vegetarian, while chicken broth adds richness if you’re not strictly vegetarian. Fresh basil stands out here, but dried basil would work if fresh isn’t available—just add less, about a teaspoon. Cherry tomatoes add sweetness and juiciness, but grape tomatoes or small roma tomatoes cut into chunks are good substitutes. The mozzarella melts beautifully, giving that classic bubbly topping. Parmesan adds a nutty sharpness, balancing the mild mozzarella.
Kitchen Tools Needed
- 8-inch (20 cm) square baking dish
- Medium saucepan
- Whisk or fork
- Wooden spoon or heatproof spatula
- Mixing bowl
- Knife and cutting board
Step-by-Step Instructions
-
Preheat the oven to 400°F (200°C). Grease an 8-inch (20 cm) square baking dish lightly with olive oil or nonstick spray to prevent sticking.
-
Bring the broth to a boil in a medium saucepan. Slowly whisk in the polenta to avoid clumping. Keep stirring until the mixture thickens—this usually takes about 3 to 5 minutes with quick-cooking polenta. You want it thick but still creamy.
-
Remove from heat and let the polenta cool for 5 minutes. This step is crucial; if it’s too hot when you add the egg, it can scramble. After it cools slightly, whisk in the egg, Parmesan, chopped basil, and a few cracks of black pepper until everything is combined.
-
Transfer the polenta mixture to your prepared baking dish. Spread it evenly with a spatula or spoon.
-
Press the halved cherry tomatoes gently into the surface of the polenta. This helps them bake into the polenta, releasing their juices without sliding off.
-
Sprinkle the shredded mozzarella evenly over the top.
-
Bake in the preheated oven for 20 to 25 minutes, or until the mozzarella is melted, bubbling, and starting to brown slightly. You’ll know it’s ready when the edges pull slightly away from the dish.
-
Remove from the oven and let the bake rest for 10 minutes. This resting time helps the polenta set, making it easier to slice and serve.
Pro Tips
- Stir the polenta constantly while cooking to avoid lumps and scorching on the bottom.
- Don’t skip the resting time after baking; cutting too soon leads to a messy crumb.
- Use fresh mozzarella if you prefer a creamier melt, but shredded mozzarella is more convenient and melts nicely.
- Taste and adjust seasoning after mixing in the egg to ensure it’s well-flavored.
- If you find your polenta gets too thick while cooling, gently stir in a tablespoon or two of warm broth to loosen it before baking.
- Pressing the tomatoes in slightly helps keep them in place and bursts their flavor into the polenta.
Common Mistakes
- Adding the egg while the polenta is too hot will cause it to scramble—always cool it first.
- Using water instead of broth can make the dish bland and less savory.
- Not greasing the baking dish well enough can cause sticking, especially on the edges.
- Baking at too low a temperature results in a watery, underbaked texture—400°F (200°C) is ideal for browning.
- Cutting into the bake immediately after baking makes it fall apart.
Variations
- Swap out cherry tomatoes with thinly sliced roasted red peppers or sun-dried tomatoes for a different tomato flavor.
- Add a handful of spinach or kale stirred in with the basil for added greens.
- For a spicy jump, sprinkle red pepper flakes into the polenta mixture.
- Use fresh herbs like oregano or thyme instead of basil to switch up the flavor profile.
Serving Suggestions
This polenta bake goes well as a main dish alongside a crisp green salad or roasted vegetables. It’s also a comforting side with grilled chicken or fish. Serve warm, sliced into squares for an easy presentation. Leftovers make a great light lunch paired with fresh greens or steamed veggies.
Storage Instructions
Store any leftovers covered in an airtight container in the refrigerator for up to 3 days. The polenta will firm up considerably in the fridge.
Reheating Tips
Reheat slices gently in a nonstick skillet over medium-low heat or in a 350°F (175°C) oven until warmed through. Adding a tiny splash of broth or water before reheating helps keep the polenta moist and creamy.
