Ingredients
- 4 tablespoons Unsalted Butter (melted)
- 6 tablespoons Extra Virgin Olive Oil (divided: 2 tbsp for garlic, 1 tbsp for onion, 3 tbsp added to sauce at the end)
- 2 cloves Garlic Cloves (smashed, not minced, to give a gentle garlic kiss)
- 7 cups Water (filtered or tap)
- 1.5 teaspoons Salt (kosher or table salt)
- 0.5 teaspoons Black Pepper (freshly ground)
- 2 cups Fine Cornmeal (coarse enough to hold shape; finer grind absorbs more moisture)
- 1.5 cups Pecorino Romano Cheese (freshly grated, for the polenta)
- 0.25 cup Half and Half (adds creaminess to the polenta)
- 1 large Onion (yellow onion, halved, cut side down)
- 1 can (15 oz) Canned Tomato Sauce (regular seasoned tomato sauce)
- 1 can (14.5 oz) Canned Whole Peeled Tomatoes (pureed before adding to sauce)
- 1.5 tablespoons Granulated Sugar (adds a subtle sweetness to the sauce)
- 0.5 teaspoons Garlic Powder (for the sauce)
- 0.5 cups Pecorino Romano Cheese (freshly grated, for the sauce)
Instructions
Infuse Butter and Olive Oil with Garlic
Melt the butter in a saucepan, add 2 tbsp olive oil, then add the smashed garlic cloves. Cook over medium heat, stirring, until the garlic turns lightly brown and the oil is fragrant (about 4 minutes). Remove garlic and set aside.
Time: PT4M
Boil Seasoned Water
Add 7 cups water, 1½ tsp salt, and ½ tsp black pepper to the saucepan. Bring to a rolling boil.
Time: PT5M
Incorporate Cornmeal
Reduce heat to medium‑low. Slowly whisk the fine cornmeal into the boiling water in a steady stream, stirring constantly to prevent lumps.
Time: PT5M
Simmer Polenta
Increase heat back to medium‑high until the mixture returns to a boil, then lower to medium‑low and let it simmer, stirring every few minutes, for about 20 minutes until thick and tender.
Time: PT20M
Finish Polenta with Cheese and Half‑and‑Half
Remove the saucepan from heat. Stir in 1½ cups grated Pecorino Romano until melted, then whisk in ¼ cup half‑and‑half until smooth.
Time: PT2M
Set Polenta in Pan
Lightly grease an 8‑inch square baking pan. Pour the polenta into the pan, smoothing the top with a spatula. Let it sit at room temperature for about 2 hours, then refrigerate for at least 3 hours until firm.
Time: PT0M
Brown the Onion
Heat 1 tbsp olive oil in a clean saucepan over medium heat. Add the halved onion cut side down and cook until the surface is nicely browned, about 4 minutes.
Time: PT4M
Puree Whole Tomatoes
While the onion browns, place the 14.5‑oz can of whole peeled tomatoes in a blender and puree for about 30 seconds until smooth.
Time: PT1M
Combine Sauce Ingredients and Simmer
Add the canned tomato sauce, pureed tomatoes, ½ cup grated Pecorino Romano, 1½ tbsp sugar, ¾ tsp salt, ½ tsp garlic powder, and the remaining 3 tbsp olive oil to the saucepan with the browned onion. Bring to a boil, then reduce to medium‑low and simmer, stirring occasionally, until the sauce thickens and flavors meld, about 15 minutes.
Time: PT20M
Portion and Bake Polenta
Remove the chilled polenta from the pan, turn onto a cutting board, and cut into six equal bricks (use a ruler if desired). Place the bricks on a parchment‑lined baking sheet and bake in a preheated 375°F oven for 30 minutes, until heated through and the edges are lightly golden.
Time: PT30M
Temperature: 375°F
Plate and Serve
Arrange the baked polenta bricks on plates and spoon the warm tomato sauce over or beside them. Serve immediately.
