Ingredients for all day tomato sauce
Eleven simple ingredients that build into a sauce with restaurant-quality depth and complexity.
| Ingredient | Amount | Notes |
|---|---|---|
| Crushed Tomatoes (46 oz can) 🍅 | 1 can | San Marzano preferred for sweetness |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Garlic Cloves 🧄 | 6 cloves | Peeled, minced finely |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity |
| Tomato Paste 🍅 | ½ cup | Squeeze tube preferred |
| Dried Oregano 🌿 | 1 tbsp | Mediterranean blend preferred |
| Dried Basil 🌿 | 1 tbsp | Or 0.25 cup fresh |
| Red Wine 🍷 | ½ cup | Bold, dry variety |
| Vegetable Broth 💧 | 1 cup | Low-sodium preferred |
| Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Sugar 🍚 | 1 tsp | Balances acidity |
The tomatoes are the foundation, and San Marzano makes all the difference—sweeter, less acidic, and with a meaty texture. Grab the 46 oz can from the Italian section at Whole Foods or Trader Joe's; it’s worth the splurge. The onion and garlic should be finely minced—almost paste-like—so they dissolve into the sauce rather than staying as distinct pieces. For the olive oil, California avocado oil or Spanish Arbequina adds a fruity note that elevates everything. If you’re using fresh basil, buy extra—you’ll want it for garnish too.
No red wine? Substitute with extra vegetable broth—just add an extra splash. Dried herbs work, but fresh basil and oregano (if available) bring that bright, aromatic punch. The tomato paste can be swapped for extra crushed tomatoes if you’re in a pinch, though it’ll be slightly thinner. For a deeper umami kick, add 1 tsp fish sauce or 1 tbsp soy sauce—trust me, it’s a game-changer. If your sauce tastes too sharp, a pinch of sugar or a splash of broth balances it out perfectly.
This sauce tastes even better the next day as the flavors meld, so make a big batch. Store in airtight containers in the fridge for up to 1 week or freeze for 6 months. For freezing, portion into 1-cup containers so you can thaw exactly what you need. Reheat gently on the stove—never microwave, or it’ll turn grainy. The longer it simmers, the richer it gets, so don’t rush it.

Step-by-step instructions for all-day tomato sauce
Transform simple ingredients into a rich, layered sauce with deep umami character.
Sauté Aromatics Until Fragrant
Heat the 0.5 cup Extra-Virgin Olive Oil in a heavy-bottomed pot over medium heat. Add the finely diced whole Yellow Onion and cook for 8-10 minutes until softened and translucent, stirring occasionally. The onions should release their sweetness without browning—this prevents bitterness in your sauce.
Reduce heat to medium-low and add the 6 cloves Garlic Cloves (minced finely). Cook for 1-2 minutes until the garlic becomes golden and fragrant—never let it burn, as it will turn bitter. Here's where the foundation of your sauce's flavor develops, so don't rush this step. The garlic should sizzle gently, filling your kitchen with that unmistakable aroma.
Build Depth with Wine and Tomato Paste
Pour in the 0.5 cup Red Wine and stir to deglaze the pot, scraping up any browned bits from the bottom. Let it simmer for 3-4 minutes until the wine reduces by half and its alcohol burns off. This step is crucial—it removes the harshness of the wine and concentrates its flavor into the sauce. You'll see the liquid reduce noticeably, leaving behind a rich, wine-infused base.
Add the 0.5 cup Tomato Paste and stir well to combine. Cook for 2-3 minutes until the paste darkens slightly and becomes fully incorporated. This creates a thick, velvety base that will prevent your sauce from being watery. The paste also deepens the tomato flavor and adds natural sweetness that balances the acidity later. Stir constantly to prevent burning at the bottom of the pot.
Simmer with Crushed Tomatoes and Herbs
Pour in the 1 can Crushed Tomatoes (46 oz) and stir to combine. Add the 1 tbsp Dried Oregano, 1 tbsp Dried Basil, 1.5 tsp Sea Salt, 0.5 tsp Black Pepper, and 1 tsp Sugar. Bring the mixture to a gentle boil, then reduce heat to low and let it simmer uncovered for 45-60 minutes. This long simmer is what develops the sauce's depth and complexity—don't skip it.
Stir occasionally to prevent the sauce from sticking. You're looking for a sauce that coats the back of a spoon and has a thick, syrupy consistency. The acidity of the tomatoes will mellow out as they cook down, and the flavors will meld together beautifully. If the sauce gets too thick, you can add a splash of 1 cup Vegetable Broth later to adjust the consistency.
Finish with Broth for Balance
After the initial 45-60 minutes of simmering, add the 1 cup Vegetable Broth to loosen the sauce slightly. Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of red wine to enhance the umami. The sauce should be rich, balanced, and full of layered flavors. Let it continue to simmer for another 15-20 minutes to allow the broth to absorb and the flavors to meld completely.
For the best results, let the sauce rest at room temperature for 10-15 minutes before serving. This allows the flavors to settle and the sauce to thicken slightly. The final product should be glossy, aromatic, and ready to elevate any pasta, pizza, or braised dish. Store any leftovers in the refrigerator for up to 5 days or freeze for 3 months—it only gets better with time.
Pro Tips For Making All Day Tomato Sauce
- Sweat the Onion First: I learned this the hard way—sautéing raw onion in olive oil until it’s soft and translucent (about 8-10 minutes) builds flavor that just simmering crushed tomatoes can’t match. Skip this, and your sauce will taste flat, no matter how long you cook it.
- Low and Slow After 30 Minutes: Once the tomato paste and crushed tomatoes hit the pot, crank the heat to boil it hard for the first 10 minutes to drive off excess water. Then drop to a bare simmer—no bubbling—and let it cook uncovered for at least 2 hours. This isn’t just about time; it’s about patience paying off.
- Salt the Crushed Tomatoes: The canned tomatoes are already salted, but don’t assume they’re seasoned enough. Add 1½ teaspoons of salt right when you dump them in—this balances acidity and lets the flavors meld properly. Taste again at the 1-hour mark; you’ll likely need another pinch.
- Toast the Garlic Last: Sounds weird, but it works: Add the minced garlic only in the final 15 minutes of cooking. This prevents it from burning into bitterness (yes, even if you’re impatient like me) and keeps its bright, fresh flavor intact. If you add it early, you’ll regret it.
Dietary considerations for this all day tomato sauce
Vegan Adaptations
This sauce is already vegan-friendly, but I make a few tweaks to amplify its depth. Swap the red wine for 1 cup vegetable broth (like Better Than Bouillon) and add 1 tsp nutritional yeast for a cheesy, umami kick.
For extra richness, stir in 1 tbsp soy sauce or 1 tsp miso paste during the final simmer—both add complexity without animal products. 🌱
Gluten-Free Options
All ingredients are naturally gluten-free, but always double-check labels on tomato paste and vegetable broth—some brands use hidden wheat. I use Annie’s Organic Tomato Paste and Imagine Gluten-Free Broth to stay safe. The sauce’s texture and flavor remain unchanged, so you won’t sacrifice depth for dietary needs. ✨
Low-Sodium Adjustments
To reduce sodium, cut the sea salt to ½ tsp and use low-sodium vegetable broth. Boost flavor with 1 tsp smoked paprika or ½ tsp onion powder—these add depth without salt.
Taste as you go, as homemade sauces often need less salt than store-bought. Your blood pressure (and taste buds) will thank you. 💪
Allergy-Free Swaps
For garlic allergies, replace the 6 cloves with 1 tbsp garlic-infused olive oil (store-bought or homemade). If tomatoes are an issue, use 1 cup tomato-free umami base (like mushroom broth or soy sauce) and thicken with cornstarch slurry. Always test small batches first—flavor safety matters! 🍄
Nut-Free & Seed-Free
This recipe is naturally nut-free and seed-free, but if you’re avoiding all seeds, skip the optional hemp seeds or pine nuts some might add as garnishes. Instead, top with fresh basil or crispy fried shallots for texture. The sauce’s flavor stands alone—no need for add-ins. 🌿
Dairy-Free & Lactose-Free
While this sauce is dairy-free by default, some recipes call for Parmesan or ricotta later. For those dishes, use nutritional yeast or vegan cheese alternatives like Violife. The sauce’s richness pairs beautifully with dairy-free toppings—just ensure your final dish aligns with your dietary goals. 🧀

Frequently asked questions
Why does this sauce need to simmer for so long?
The long simmer (at least 1 hour) is what transforms basic ingredients into a restaurant-quality sauce. This time allows the tomatoes to break down, releasing natural sugars and deepening the umami flavor. It also lets the alcohol from the wine fully cook off, preventing any harshness. The result is a sauce with complex layers of flavor that you won't get from quick cooking methods.
Can I make this sauce in a slow cooker?
Use the same ingredients but adjust the cooking time. After sautéing the onions and garlic, add everything (including the broth) to your slow cooker and cook on low for 6-8 hours or high for 3-4 hours. The slow cooker's gentle heat will create the same depth of flavor without requiring constant attention. Just stir occasionally to prevent sticking.
How can I tell when the sauce is done?
The sauce is ready when it coats the back of a spoon with a thick, velvety consistency and has reduced by about 1/3 of its original volume. It should smell rich and aromatic with no raw tomato taste. For a final check, let it cool slightly and taste—it should be balanced with sweetness, acidity, and savory depth. If it's too thick, add a splash of broth; if too thin, simmer uncovered for another 10-15 minutes.
What's the best way to store leftovers?
Transfer the cooled sauce to airtight containers and store in the refrigerator for up to 5 days. For longer storage, portion into 1-cup containers and freeze for up to 3 months. When reheating, do it gently on the stove over low heat—never microwave, as this can make the sauce grainy. The flavors actually improve after refrigeration as the ingredients meld further.
Can I add meat to this sauce?
Yes! For a meaty version, brown 1 pound of ground beef, Italian sausage, or pancetta first, then proceed with the recipe. Add the meat after the wine has reduced but before adding the crushed tomatoes. Drain any excess fat if needed. The meat will infuse the sauce with its own rich flavors while keeping the tomato base intact. This works especially well for lasagna or meatballs.
