Ingredients

• Olive oil – 2 cups (about 480 ml)
• Large onions, chopped – 10 large (about 3.5 lbs or 1.6 kg)
• Garlic cloves, minced – 40 cloves (about 1 1/3 cups minced garlic)
• Carrots, finely chopped – 10 medium (about 2.5 lbs or 1.1 kg)
• Celery stalks, chopped – 10 stalks (about 2.5 lbs or 1.1 kg)
• Canned crushed tomatoes – 15 quarts (about 15 x 28 oz cans)
• Tomato paste – 4 cups (about 2 cans of 28 oz each)
• Water or low-sodium vegetable broth – 4 quarts (about 4 liters)
• Dried oregano – 1/2 cup (about 8 tablespoons)
• Dried basil – 1/2 cup (about 8 tablespoons)
• Salt – 1/4 cup (adjust to taste)
• Black pepper – 3 tablespoons (or to taste)
• Red pepper flakes (optional) – 2 teaspoons
• Fresh parsley, chopped – 1 cup (for garnish, optional)

Instructions

1. Prepare your workspace: gather all ingredients, large stockpots, stirring utensils, and measuring tools. Since this is a large batch, use at least two 20-quart stockpots or one very large commercial-sized pot.
2. Heat the olive oil in the large pot(s) over medium heat. Once shimmering, add the chopped onions, carrots, and celery. Sauté, stirring occasionally, until the vegetables are soft and fragrant, about 10-12 minutes.
3. Add the minced garlic to the vegetable mixture and cook for another 2 minutes, stirring constantly to prevent burning.
4. Pour in the crushed tomatoes and tomato paste. Stir well to combine all ingredients thoroughly.
5. Add water or vegetable broth to the mixture, stirring to loosen the sauce and achieve your desired consistency. For a thicker sauce, use less liquid; for a thinner, more soup-like sauce, add more.
6. Season the sauce with dried oregano, basil, salt, black pepper, and red pepper flakes if using. Stir well to evenly distribute the herbs and spices.
7. Bring the sauce to a gentle boil over high heat, then reduce the heat to low. Cover the pot(s) partially to allow steam to escape, and simmer gently for at least 2 hours, stirring occasionally. For deeper flavor, you can simmer for up to 4 hours, adding more water if the sauce thickens too much.
8. During the last 30 minutes of simmering, taste and adjust seasoning as needed. Remove from heat and stir in chopped fresh parsley if desired.
9. Serve hot over cooked spaghetti or your preferred pasta. For large servings, keep the sauce warm in a slow cooker or chafing dish if not serving immediately.

Tips

• Substitutions: Feel free to substitute fresh herbs for dried if available, using about three times the amount. You can also add ground beef or turkey during the sautéing step for a meaty sauce.
• Storage: Store leftover sauce in airtight containers in the refrigerator for up to 4 days or freeze in portions for up to 3 months. Thaw in the refrigerator overnight before reheating.
• Common mistakes: Avoid over-salting early; it’s best to taste and adjust seasoning at the end. Also, don’t rush the simmering process—slow cooking develops flavor.
• Cooking pasta: Cook pasta separately in salted boiling water just before serving, according to package instructions. Drain and toss with a little olive oil to prevent sticking.

Serving Suggestions

Serve the hot spaghetti sauce over freshly cooked spaghetti or your favorite pasta. Complement with grated Parmesan cheese, a side of garlic bread, and a fresh green salad for a complete meal. For a more festive presentation, sprinkle chopped fresh basil or parsley on top just before serving.

Variations

For a vegetarian version, omit any meat and add sautéed mushrooms, zucchini, or bell peppers for added flavor and texture. To make it spicier, increase red pepper flakes or add chopped hot peppers. You can also incorporate olives or capers for a Mediterranean twist, or add a splash of red wine during simmering for depth.

Storage and Reheating

Allow the sauce to cool completely before storing in airtight containers. In the refrigerator, it keeps well for up to 4 days. To reheat, warm it gently over low heat on the stovetop, stirring occasionally. For larger quantities, reheating in a slow cooker on low for 1-2 hours ensures even warming without burning. If frozen, thaw overnight in the fridge and reheat similarly.

Frequently Asked Questions

Can I prepare this sauce ahead of time?

Yes, this sauce actually improves in flavor when made a day in advance. Prepare it, let it cool, then store in the refrigerator for up to 2 days before reheating and serving.

How do I scale this recipe for fewer people?

Simply reduce the ingredient quantities proportionally. For example, halving the recipe for 50 people involves halving each ingredient. Use smaller pots and adjust simmering times accordingly.

What if I don’t have canned crushed tomatoes?

You can substitute fresh tomatoes—blanch, peel, and crush about 15 pounds (6.8 kg) of ripe tomatoes. Cook them down to your desired consistency before adding the other ingredients. This adds freshness but requires more prep time.

How can I make this sauce gluten-free?

This sauce is naturally gluten-free. Just ensure that any additional ingredients or additives, like tomato paste, are labeled gluten-free. Serve over gluten-free pasta or rice for a full gluten-free meal.

Is it necessary to simmer for 2 hours?

Longer simmering enhances flavor and thickens the sauce, but you can reduce the cooking time to 1 hour if needed. Just taste and adjust the seasoning before serving. For a richer sauce, simmer longer.

Can I add meat to this sauce?

Absolutely. Brown ground beef, Italian sausage, or chopped meat during the initial sauté step with the vegetables. Drain excess fat before adding the tomatoes, and simmer as directed for a meaty, hearty sauce.
