Easy Homemade Tomato Basil Sauce Recipe

This easy homemade tomato basil sauce recipe makes about 4 cups of rich, fresh-tasting sauce in roughly 45–55 minutes. Made with canned whole peeled tomatoes, onion, garlic, olive oil, and fresh basil, it is the perfect amount for tossing with 12–16 ounces of cooked pasta.

The flavor is bright, savory, and comforting, with gently softened onion, fragrant garlic, and sweet tomato richness balanced by fresh basil. A slow uncovered simmer allows the tomatoes to break down and concentrate naturally, so you get a satisfying sauce without relying on a large amount of tomato paste or sugar.

Why You’ll Love This Recipe

This tomato basil sauce is the kind of dependable recipe that turns a few pantry staples into a memorable dinner. It is straightforward enough for a weeknight, yet the long, gentle simmer gives it the rounded flavor of a sauce that has been cooking all afternoon.

Whole peeled tomatoes provide a pleasantly tender texture and allow you to decide how smooth or rustic the finished sauce will be. The onion melts into the tomatoes, garlic brings savory warmth, and fresh basil added near the end keeps its delicate aroma lively.

• Simple ingredients: Everything is easy to find, with no complicated preparation.
• Flexible texture: Blend it smooth or leave it chunky.
• Useful yield: About 4 cups is enough for 12–16 ounces of pasta.
• Make-ahead friendly: The sauce can be cooled, stored, and gently reheated.

If you are planning an Italian-inspired meal, serve pasta first and follow it with a slice of savory tomato pie for a tomato-forward menu.

Ingredients You’ll Need

Start with two 28-ounce cans of whole peeled tomatoes, preferably San Marzano-style. Good-quality tomatoes matter because they form nearly all of the sauce, and crushing them yourself usually gives a better texture than using pre-diced tomatoes.

• 2 tablespoons extra-virgin olive oil
• 1 medium yellow onion, finely diced
• 3 garlic cloves, minced or thinly sliced
• 2 cans, 28 ounces each, whole peeled tomatoes
• 1 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper, optional
• 1/2 cup loosely packed fresh basil leaves, torn or chopped
• 1/4 teaspoon red-pepper flakes, optional
• 1 teaspoon sugar, optional only if the tomatoes taste notably acidic

The sugar is not a standard requirement. Taste the sauce after it has simmered, and add it only when the tomatoes have a notably sharp acidity that salt alone does not balance.

For serving, have 12–16 ounces of cooked pasta ready, along with a little extra olive oil and grated Parmesan or Pecorino if you enjoy a cheesy finish.

How to Make It Step-by-Step

Step 1: Crush the tomatoes before you begin cooking, either by hand in a bowl or directly in the saucepan with a wooden spoon. Breaking them up first helps them blend into the onion and garlic more quickly while the sauce simmers.

Step 2: Heat the olive oil in a large saucepan or Dutch oven over medium heat. Add the diced onion and cook for 5–7 minutes, stirring occasionally, until it is soft and translucent but not browned; this gentle start creates a sweet, mellow foundation.

Step 3: Add the garlic and the optional red-pepper flakes. Cook for 30–60 seconds, stirring constantly, just until fragrant, because garlic can turn bitter if it becomes dark.

Step 4: Add the crushed tomatoes, kosher salt, and optional black pepper. Stir thoroughly and bring the mixture to a gentle simmer, watching for steady small bubbles rather than a rapid boil.

Step 5: Simmer the sauce uncovered for 30–40 minutes, stirring occasionally. The tomatoes should break down and the sauce should become slightly thicker, while the open pot allows excess moisture to evaporate naturally.

Step 6: Stir most of the basil into the pot during the final 5 minutes. Taste the sauce and adjust the salt; add the optional sugar only if the tomatoes taste notably acidic.

Step 7: Remove the pot from the heat and stir in the remaining basil. Blend carefully with an immersion blender for a smooth sauce, or leave it chunky for a rustic, spoonable texture.

Step 8: Toss the sauce with 12–16 ounces of cooked pasta, adding a final drizzle of olive oil if desired. Finish each serving with Parmesan or Pecorino for a salty, creamy contrast.

Chef’s Tips for the Best Tomato Basil Sauce

Do not rush the onion. Cooking it until soft and translucent without browning gives the sauce a gentle sweetness and prevents the finished dish from tasting harsh.

Keep the simmer uncovered and moderate. A rapid boil can make the sauce splatter and cook unevenly, while a gentle simmer steadily concentrates the tomato flavor without requiring lots of tomato paste or sugar.

Add basil in two stages for the freshest result. Most of it goes in during the final 5 minutes so it flavors the sauce, and the remaining leaves are stirred in off the heat so their aroma stays bright.

If the sauce tastes flat, check the salt before adding sugar. Tomatoes often need a little more seasoning, but sugar should be reserved for tomatoes that remain notably acidic after cooking and tasting.

For a rustic sauce, use a wooden spoon to break down larger tomato pieces and stop when you like the texture. For a smooth sauce, use an immersion blender carefully after removing the pot from the heat, taking care to avoid splashes.

Serving Ideas and Pairings

The classic use is simple: toss this sauce with hot cooked pasta and finish with grated Parmesan or Pecorino. Spaghetti, linguine, penne, and rigatoni all work well, with short shapes especially good at catching the rustic tomato pieces.

You can also spoon the sauce over cooked vegetables, baked chicken, or meatballs. Keep a little extra sauce on the table so everyone can add more to their plate without drying out the pasta.

A crisp green salad or roasted vegetables balances the richness of the dish. If you are serving bread, try a warm piece of cornbread on the side; a batch of spicy honey cornbread muffins adds a sweet-and-savory contrast.

For a casual dessert spread, serve small treats such as easy homemade beignets after the pasta. Their light, crisp texture provides a pleasant change from the silky sauce.

Storage, Freezing, and Reheating

Let leftover sauce cool before transferring it to a covered container. Refrigerate it and use it within a few days, reheating gently in a saucepan over low to medium-low heat until hot throughout.

If the sauce becomes thicker in the refrigerator, loosen it with a small splash of water while reheating. Stir often and avoid an aggressive boil, which can cause splattering and make the sauce reduce too far.

The sauce is also useful for advance meal preparation. Divide it into practical portions before chilling so you can warm only what you need for one dinner, then toss it with freshly cooked pasta.

For a special homemade treat after storing dinner portions, make a small dessert batch of homemade peanut butter cups.

Method

 

Step-by-Step

1. Crush the whole tomatoes by hand in a bowl, or add them to the saucepan and crush them with a wooden spoon. Set them aside so they are ready when the onion and garlic are softened.
2. Heat the olive oil in a large saucepan or Dutch oven over medium heat. Add the diced onion and cook for 5–7 minutes, stirring occasionally, until soft and translucent but not browned.
3. Add the garlic and red-pepper flakes, if using. Cook for 30–60 seconds, stirring constantly, just until the garlic is fragrant and the flakes begin to perfume the oil.
4. Add the crushed tomatoes, kosher salt, and black pepper. Stir well, then bring the mixture to a gentle simmer rather than a rapid boil.
5. Simmer the sauce uncovered for 30–40 minutes, stirring occasionally, until slightly thickened and the tomatoes have broken down. Keep the heat moderate and adjust it as needed to prevent aggressive bubbling.
6. Stir most of the basil into the sauce during the final 5 minutes of cooking. Taste carefully and adjust the salt; add the optional sugar only if the tomatoes taste notably acidic.
7. Remove the saucepan from the heat and stir in the remaining basil. For a smooth sauce, blend carefully with an immersion blender, or leave it chunky for a rustic texture.
8. Toss the finished sauce with 12–16 ounces of cooked pasta. Serve with a drizzle of olive oil and grated Parmesan or Pecorino, if desired.

Notes

Use good-quality canned whole tomatoes and crush them yourself for the best texture. Store cooled sauce in the refrigerator and reheat gently; simmering uncovered is preferable to adding lots of tomato paste or sugar.
