Begin by preheating your oven to 425°F (220°C). This temperature is perfect for roasting those beefsteak tomatoes to perfection.

Cut each tomato in half and remove the stem area. This little detail may seem minor but ensures a cleaner taste and texture.

Place the tomatoes, cut side down, onto a greased baking sheet. Drizzle a pinch of salt over them—this will help reduce moisture and concentrate their flavor. Transfer the baking sheet to the oven and roast the tomatoes for about 35-45 minutes until they're tender and their skins start to wrinkle.

Once out of the oven, let the tomatoes cool for about 5 minutes. This cooling time makes handling easier. Provide a bit of gentle coaxing with your tongs or fingers to remove the skins—watch as they slip off effortlessly!

Now, it’s time for some good old-fashioned crushing. Using either your clean hands or a potato masher, thoroughly crush the tomatoes until you achieve your desired consistency. You’ll want some chunkiness for texture.

While those beauties are roasting, heat the olive oil in a skillet over medium heat. Add your diced onions, letting them sizzle for about 5 minutes until they're translucent. Then toss in the minced garlic and cook for an additional minute, just until fragrant.

Grab those chopped fresh herbs and toss them in the skillet. Pour in your dry red wine and beef stock, giving everything a good stir. This mixture is your flavor base. Let it cook down for about 5 minutes until most of the liquid has evaporated.

Now, take this aromatic mix and transfer it into a large Dutch oven. This adds depth as the sauce cooks. Stir in your roasted tomatoes—be sure to chop up any larger pieces. Add in the tomato paste and stir until well incorporated.

Cover the pot and let it simmer on low heat for 1 hour, letting all those flavors marry beautifully. After the hour, remove the lid and allow it to simmer for an additional hour. This slow cooking is key to developing a rich flavor profile.

You can now pour this fabulous sauce over pasta, use it as a pizza base, or incorporate it into your favorite dish that calls for tomato sauce. Enjoy the fruits of your labor!
