How To Make Spaghetti Sauce From Tomato Paste

I first made this spaghetti sauce during the pandemic, when we weren’t making many trips to the grocery store and I needed to work with what we already had in the pantry.

With one can of tomato paste, a few seasonings and about 25 minutes, I discovered I could make a rich, savory sauce without a jar of pasta sauce or any other canned tomatoes.

To make spaghetti sauce from tomato paste, whisk the paste with water, sugar and seasonings, then let everything simmer for 20 minutes until smooth and flavorful. Spoon it over cooked spaghetti for an inexpensive, filling dinner made entirely from pantry staples.

This recipe makes approximately 2 cups of spaghetti sauce, enough for about 8 ounces of pasta.

Why This Recipe Works

• It turns one can of tomato paste into a complete spaghetti sauce. You don’t need canned tomatoes, fresh tomatoes or a jar of pasta sauce. If you have more ingredients and time, try my homemade pasta sauce for a more robust, slow-simmered version.
• It uses simple pantry ingredients. Water, sugar and dried seasonings transform concentrated tomato paste into a rich, savory sauce.
• Dinner is ready in about 25 minutes. The sauce requires only a few minutes of prep followed by a 20-minute simmer, giving the seasonings time to blend while creating a smooth, spoonable consistency.
• It’s easy to adjust. Add a little more water for a thinner sauce, simmer it longer to thicken it or tweak the seasonings to suit your family.

Ingredient Notes

Tomato paste – One 6-ounce can of tomato paste forms the rich tomato base of this sauce. No canned tomato sauce, crushed tomatoes or fresh tomatoes are needed.

Water – Mixing 1 1/2 cups of water with the tomato paste gives the sauce a smooth, spoonable consistency. If the sauce becomes thicker than you prefer as it simmers, stir in a little additional water.

Sugar – Sugar balances the acidity and concentrated flavor of the tomato paste. You can reduce or omit it for a more savory sauce.

Seasonings – Oregano, Italian seasoning, onion powder, garlic powder, salt and pepper give the sauce its classic Italian-inspired flavor.

How To Make Spaghetti Sauce From Tomato Paste

1. Combine the ingredients. Add the tomato paste, water, sugar, oregano, Italian seasoning, salt, pepper, onion powder and garlic powder to a medium saucepan.

2. Stir until smooth. Whisk or stir until the tomato paste is fully incorporated and the mixture is smooth. Bring the sauce to a boil over medium-high heat.

3. Simmer the sauce. Reduce the heat to medium-low and simmer uncovered for 20 minutes, stirring occasionally. The sauce will thicken slightly and deepen in color as it cooks. Taste and adjust the seasonings, adding a splash of water if the sauce is thicker than you prefer.

Spoon the sauce over al dente pasta and top with grated Parmesan cheese, if desired.

Recipe Variations

• Add ground meat. Brown ground beef, Italian sausage or ground turkey and drain off any excess grease. Add the remaining sauce ingredients directly to the skillet and continue cooking as directed.
• Add some heat. Stir in a pinch of crushed red pepper flakes or a dash of cayenne pepper.
• Add vegetables. Sauté chopped onion, bell peppers or mushrooms in a small amount of olive oil until softened. Add the remaining sauce ingredients to the skillet and continue cooking as directed.
• Make it extra garlicky. Add an additional 1/4 teaspoon of garlic powder, then taste the finished sauce and adjust as needed.

How To Store and Reheat Spaghetti Sauce

Refrigerate. Allow the sauce to cool slightly, then transfer it to an airtight container and refrigerate for up to 5 days.

Freeze. Let the sauce cool completely, then freeze it in an airtight container or freezer bag for up to 3 months. Thaw it overnight in the refrigerator.

Reheat. Warm the sauce in a saucepan over medium-low heat, stirring occasionally. If it has thickened during storage, stir in a splash of water until it reaches your preferred consistency.
