Ingredients & Instructions
Ingredients
Spinach and Cheese Layer
- 40 g unsalted butter
- 1 tbsp minced garlic (chunky or finely chopped)
- ¼ tsp kosher salt
- ¼ tsp black pepper
- 6 cups baby spinach leaves
- ¼ tsp cayenne pepper
- 2 cups ricotta cheese
- 2 cups cheddar cheese, grated (reserve 1 tbsp for topping)
- ½ cup parmesan cheese, finely grated (reserve 1 tbsp for topping)
- ½ cup pecorino romano cheese, finely grated (reserve 1 tbsp for topping)
- 2 tbsp finely grated lemon zest
Polenta Layer
- 2 cups polenta (coarse cornmeal)
- ½ tsp kosher salt
- 2 cups room temperature water
- 2½ cups boiling water
- 40 g unsalted butter
Optional Garnish
- Freshly ground black pepper
- Finely chopped parsley
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 180°C (350–375°F). Grease or spray a medium-sized baking dish (about 9×13 inches) with nonstick cooking spray or a light coating of butter. This prevents sticking and ensures easy serving later.
2. Cook the Spinach Mixture
In a large frying pan over high heat, melt butter until it starts to foam slightly. Add garlic, salt, and pepper, cooking for about 1 minute until fragrant.
Add the spinach leaves and cayenne pepper, stirring until the spinach wilts—this should take just 1–2 minutes. Remove from heat and allow it to cool slightly.
3. Prepare the Cheese Filling
In a large mixing bowl, combine the ricotta, cheddar, parmesan, and pecorino romano cheeses. Add the lemon zest for a touch of brightness and the cooked spinach mixture. Stir until evenly blended.
This creamy mixture will form the flavorful middle layer of your bake—rich, cheesy, and balanced with a subtle hint of lemon and spice.
4. Cook the Polenta
Without washing the pan, place it back on high heat. Add the polenta and salt, then pour in the room-temperature water. Stir constantly with a whisk or wooden spoon to prevent lumps.
Gradually add the boiling water, continuing to stir until the mixture thickens and starts to pull away from the sides of the pan (this usually takes 5–8 minutes). Stir in the butter until melted and smooth.
Pro Tip: For ultra-creamy polenta, add a splash of milk or cream once the texture thickens.
5. Assemble the Layers
Spread half of the polenta evenly over the bottom of your prepared baking dish. Use a spatula to smooth it into an even base layer.
Next, spoon the spinach and cheese mixture over the polenta, spreading it evenly from edge to edge.
Finally, top with the remaining polenta, smoothing it to completely cover the filling.
6. Add the Topping
Sprinkle the reserved cheddar, parmesan, and pecorino romano cheeses evenly across the top. This blend creates a golden, crispy crust that adds irresistible texture and flavor once baked.
7. Bake Until Golden
Place the dish on the middle oven rack and bake for 20–25 minutes, or until the top is golden and lightly crisped. The edges should bubble slightly, and the aroma will fill your kitchen with cheesy, garlicky warmth.
8. Garnish and Serve
Once baked, remove from the oven and let it cool for about 5 minutes before slicing. Sprinkle with black pepper and fresh parsley for a vibrant finish.
Serve warm as a main course with a crisp salad or as a side dish alongside grilled chicken, roasted vegetables, or Italian sausages.
Cooking Tips & Variations
This dish is wonderfully flexible. Here are a few ideas to help you make it your own:
1. Add Layers of Flavor
For added richness, mix a few tablespoons of cream cheese or mascarpone into the spinach filling. It adds a luxurious, velvety texture.
2. Make It Spicier
If you enjoy a little kick, double the cayenne pepper or add a pinch of crushed red chili flakes to the spinach mixture.
3. Cheese Substitutes
Swap in your favorite cheeses: mozzarella for stretchiness, gruyère for nuttiness, or fontina for a smooth melt.
4. Gluten-Free Friendly
This recipe is naturally gluten-free since polenta is made from cornmeal, making it a great choice for those avoiding gluten.
5. Make Ahead
Polenta Al Forno can be assembled a day in advance. Store it covered in the refrigerator, then bake just before serving. Leftovers also reheat beautifully—perfect for meal prep.

FAQs
1. Can I use frozen spinach instead of fresh?

Absolutely. Use vegan butter, plant-based ricotta, and nutritional yeast instead of parmesan and pecorino for a dairy-free version.
4. How do I keep the polenta smooth?
Whisk constantly while adding liquid and cook over moderate heat to prevent lumps.
5. Can this be served cold?
Yes! Once cooled, it firms up nicely and can be served in slices—delicious with a drizzle of olive oil or tomato sauce.
