Method

01

Prepare the Vegetables

Wash the tomatoes thoroughly and dice them into small pieces. Slice the leek into thin rounds and rinse well under cold water to remove any trapped dirt between the layers. Mince the garlic and set everything aside before cooking.

02

Sauté the Leeks

Melt the butter in a large skillet over medium heat. Add the sliced leeks and cook for about 4–5 minutes until softened and fragrant. Stir occasionally to prevent browning. Add the minced garlic during the final minute and cook just until fragrant.

Cook the Tomatoes

Add the diced tomatoes and salt to the skillet. Stir well, cover with a lid, and cook for 5–7 minutes until the tomatoes soften and release their juices. Stir occasionally to prevent sticking.

Finish the Sauce

Pour in the cooking cream and stir until smooth. Add the oregano and cane sugar, then simmer gently for another 3–5 minutes until the sauce becomes creamy and slightly thickened. Taste and adjust the seasoning with additional salt or freshly ground black pepper if desired.

Frequently asked questions

Can I use canned tomatoes?

Yes. One 14-ounce can (400 g) of diced tomatoes works well when fresh tomatoes are out of season.

Can I make it dairy-free?

Yes. Replace the butter with olive oil and use an unsweetened plant-based cooking cream.

What pasta works best?

Penne, rigatoni, fettuccine, and tagliatelle all hold the creamy sauce beautifully.

Can I add protein?

Absolutely. Grilled chicken, Italian sausage, shrimp, or sautéed mushrooms all pair well with this sauce.
