- Garlic cloves (2, minced): Infuses the sauce with aromatic warmth without overpowering.
- Tomato paste (1 tablespoon): Intensifies the tomato flavor and thickens the sauce for a luscious finish.
- Fresh basil (1/4 cup, chopped): Freshness that brightens the sauce with herbal notes and a fragrant finish.

How to Make How to Make Pasta Sauce from Fresh Tomatoes Recipe
Step 1: Prepare the Onion
Start by shredding the yellow onion using a box grater. This technique allows the onion to melt effortlessly into the sauce, creating a delicate sweetness and a lovely, silky texture that you just can’t achieve by chopping.
Step 2: Shred the Tomatoes
Next, cut your tomatoes in half and grate them just like the onion. This step effortlessly separates the juicy flesh from the skins, which you discard. The grated tomatoes will melt down into a vibrant, fresh base for your sauce.
Step 3: Heat the Olive Oil
Warm the olive oil in a large pot over medium-high heat. This fruity oil will be the foundation that sautés our onion and garlic, drawing out their flavors gently and preparing them for the fresh tomato addition.
Step 4: Sauté Onion and Garlic
Toss in the shredded onion and cook for about 5 minutes, stirring now and then to keep it from browning too much. Then add in the minced garlic and sauté for just 30 seconds to release its aroma without turning bitter. This step is where the sauce starts building its lovely flavor profile.
Step 5: Add Tomatoes and Tomato Paste
Pour in the grated tomatoes along with the tablespoon of tomato paste. Stir everything together and bring the mixture to a gentle simmer. Let it cook slowly for 20 minutes, stirring occasionally to help it thicken and develop that deep tomato goodness.
Step 6: Finish with Basil and Butter
Once removed from the heat, fold in the chopped fresh basil and the butter. The basil adds fragrant brightness, while the butter smooths out the sauce, making it irresistibly luscious and rich.
Step 7: Serve with Pasta
Mix this vibrant sauce with about 1 pound of your favorite cooked pasta. The sauce clings beautifully to every strand or nook, ensuring each bite is bursting with fresh tomato flavor.
Step 8: Optional Parmesan Topping
Finish off with a sprinkle of parmesan cheese if you like, adding a salty, nutty touch that complements the sauce perfectly. Serve immediately for the best taste and texture.
Step 9: Refrigerate or Freeze
If you have leftovers, store your sauce in the fridge for up to 4 days or freeze in airtight containers for up to 6 months, so the love can continue well beyond dinner.
How to Serve How to Make Pasta Sauce from Fresh Tomatoes Recipe

Garnishes
Fresh basil leaves and a dusting of parmesan cheese are classic options that lift the sauce’s vibrant flavors. You can also try a drizzle of high-quality extra virgin olive oil or a few red pepper flakes for a gentle kick.
Side Dishes
This sauce pairs wonderfully with simple garlic bread to soak up every last drop, or a crisp green salad dressed with lemon and olive oil to balance the richness of the butter in the sauce.
Creative Ways to Present
For a charming twist, serve the sauce over roasted vegetable noodles or use it as a base for a baked pasta dish topped with melted mozzarella. Even a spoonful on a warm skillet of polenta creates a comforting plate of pure joy.
Make Ahead and Storage
Storing Leftovers
Keep your fresh tomato pasta sauce in an airtight container in the refrigerator for up to four days. It’s best to let the sauce cool completely before sealing to maintain its bright flavor and vibrant color.
Freezing
Freezing is a fantastic option for preserving this sauce’s freshness. Portion it into freezer-safe containers or bags and freeze for up to six months. Thaw in the refrigerator overnight before reheating.
Reheating
Reheat gently on the stovetop over low heat, stirring occasionally until warmed through. This careful reheating preserves the fresh tomato flavor and keeps the sauce silky without breaking.
FAQs
Can I use any type of tomatoes for this sauce?
Absolutely! While San Marzano or Roma tomatoes are ideal for their sweetness and low moisture, mixing different types like heirloom or Campari adds layers of flavor and color that make the sauce truly special.
Do I have to peel the tomatoes before grating?
No need at all. Grating the tomatoes separates the skin naturally, which you can just discard. This saves time and keeps the sauce smooth without unwanted bits of skin.
How long can I store the pasta sauce in the refrigerator?
The sauce keeps well in the fridge for about four days. Beyond that, the fresh tomato flavor starts to fade, so freeze extras if you want to keep it longer.
Can I add other herbs besides basil?
Definitely! While fresh basil is traditional and pairs perfectly with fresh tomatoes, you can experiment with oregano, thyme, or even a pinch of rosemary for a different herbal note.
Is this sauce suitable for freezing after adding butter?
Yes, butter adds richness and the sauce freezes beautifully. Just be sure to stir well when reheating so the butter reincorporates smoothly into the sauce.
