- It makes a quick easy meal over plain pasta or it works well with vegan stuffed peppers, baked ziti, stuffed shells, ravioli, or lasagna.
🧾 Ingredients and substitutions
- Tomatoes - about 10 Roma or other medium-sized ripe tomatoes work best. The riper the tomatoes, the sweeter and more flavorful the sauce.
- Garlic - for flavor. A clove or two will flavor the sauce well. You can use 1/4 teaspoon of garlic powder if you don't have fresh garlic.
- Basil - or any other fresh herbs. If you don't have fresh, about 1 teaspoon of dried basil or Italian seasoning will work.
- Olive Oil - this is important for making a rich and creamy sauce. You can reduce the amount of oil a little if you wish, but some oil it's important for the texture of the sauce.
- Salt - for flavor. Feel free to adjust to your taste.
🥄 How to make oven-roasted tomato sauce
Step 1 - Simply cut tomatoes in half and put them cut side down on a cookie sheet.
Step 2 - Roast them in the oven at 350° F for about 30 minutes until the skins start to wrinkle.
Step 3 - Then place the tomatoes and their juices, along with some basil and olive oil in a blender. (You may have to do this in 2 batches depending on the size of your blender. Don't fill it over 3/4 of the way full or it could come out of the top and burn you).
Step 4 - Blend for about 30 seconds until creamy.
Step 5 - Pour over your choice of pasta, or use it in vegan ravioli, vegan stuffed shells, vegan baked ziti, or vegan lasagna.
🌿 Flavoring the sauce
Basil is my favorite herb to use in this sauce. You can just throw in a fresh handful while you blend it or you can use some vegan pesto. If you don’t like the flavor of basil, substitute it with oregano or any other herbs that you like.
Tip: Big batches of vegan pesto are great to keep in the freezer, so it is ready to use in soups and sauces. I pour my pesto into ice cube trays and then put them into freezer bags.
If you like the flavor of roasted red peppers, try my tomato and red pepper pasta sauce.
❔ Why is it so creamy?
There is no milk or cream in the recipe, so I’m not exactly sure why it tastes so creamy, but something magical happens with the oil mixes with the acid in the tomato. If you want to eliminate or reduce the oil, feel free. It will just be a lighter and less creamy sauce.
👩🏻🍳 Pro Tips
- Make sure that you don’t overcook your tomatoes or they will dry out. They should have wrinkled skin and there should be juice on the cookie sheet.
- If you accidentally get them too dry, just add a little water while blending until you achieve a good consistency.
- Make this in the summer with fresh ripe tomatoes from the garden, and it will need no added sugar. I only add sugar if the tomatoes are not in season and are therefore not as naturally sweet.
- Don't fill your blender with more than 2 cups of tomatoes at a time to ensure that it doesn't overflow and burn you.
- You can also put the roasted tomatoes into a large bowl or pot and use an immersion blender.
Serve this oven-roasted tomato sauce over pasta with some homemade vegan focaccia bread, vegan drop biscuits, or vegan garlic knots on the side!

Could this recipe be used for canning?
Hi Kathleen, I think that it could be used for canning, but I have never done it! Canning is something that I used to do as a child with my parents and grandparents, but I've never been brave enough to do it myself. I need to go spend a week with my parents and get a canning lesson! If I do, I will comment here and let you know how it goes. 🙂
This was the easiest way to make homemade tomato sauce! I love how it is fresh tasting yet creamy too! Thanks so much for this recipe!
