- prep
Preheat the oven and prepare the baking dish.
Preheat the oven to 375°F (190°C). Grease a 9x13 inch baking dish with a little olive oil or butter.

Cook the polenta.
1.Bring 6 cups of water to a rolling boil in a large saucepan.2.Add 1/2 teaspoon of salt to the water.3.Slowly whisk in the polenta in a steady stream to prevent lumps.4.Reduce the heat to low and cook, stirring frequently, until very thick and pulling away from the sides of the pan, about 20-25 minutes.5.Remove from heat and stir in the butter and 1/2 cup of grated parmesan cheese until melted and smooth.TIPConstant stirring is key. If it gets too thick too fast, add a splash of water to loosen it. - prep · ~10 min
Spread the polenta layer.
Pour the hot polenta into the greased baking dish. Spread it into an even layer across the bottom using a spatula. Let it cool and set for 10 minutes while you make the sauce.
TIPA slightly wet spatula prevents the polenta from sticking to it while spreading. - saute · ~15 min
Brown the meat and aromatics.
1.Heat the olive oil in a large skillet over medium-high heat.2.Add the chopped onion and cook until softened and translucent, about 4-5 minutes.3.Add the minced garlic and cook for 30 seconds until fragrant.4.Add the ground beef, 1/4 teaspoon salt, and a pinch of black pepper. Cook, breaking it up with a spoon, until browned, about 6-8 minutes.5.Stir in the dried oregano, dried basil, and red pepper flakes.TIPAvoid overcrowding the pan to ensure the beef browns rather than steams. - simmer · ~18 min
Build the meat sauce.
1.Add the tomato paste to the skillet and cook for 2 minutes, stirring constantly to caramelize it slightly.2.Pour in the crushed tomatoes and bring to a simmer.3.Reduce the heat to low and let it bubble gently for 15 minutes, stirring occasionally, until the sauce thickens.TIPA splash of water can be added if the sauce becomes too dry before the flavors meld. - mix

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Whisk the polenta into boiling water in a thin, steady stream to prevent lumps from forming.
- 2Stir the polenta frequently as it cooks; it will thicken quickly and can scorch if left unattended.
- 3Let the polenta layer cool and set for a full 10 minutes before adding toppings so it holds together.
- 4Brown the ground beef in batches if needed to get a deep sear, not a gray steam.
- 5Caramelize the tomato paste for 2 minutes to deepen the sauce's savory richness.
- 6Let the finished lasagna rest for 10–15 minutes after baking so the layers set for clean slices.
- 7If the top browns too fast, tent loosely with foil for the remaining bake time.
