Ingredients

Gather these fresh, high-quality ingredients for your spaghetti sauce canning adventure:

• 30 lbs fresh tomatoes (Roma or San Marzano varieties work best)
• 2-1/2 lbs ground meat (beef, sausage, venison, or turkey – your choice!)
• 5 cloves garlic, freshly minced
• 1 cup onions, finely chopped
• 1 cup celery or green peppers, chopped (use one or a mix)
• 1 lb fresh mushrooms, sliced (optional but recommended for depth of flavor)
• 4-1/2 tsp salt (adjust to taste)
• 2 tbsp dried oregano
• 4 tbsp fresh parsley, minced
• 2 tsp black pepper, freshly ground
• 1/4 cup brown sugar (balances the tomatoes’ acidity)

Pro Tip: For a vegetarian version, simply omit the meat and add an extra pound of mushrooms and a cup of cooked lentils for protein.

Timing

• Prep Time: 45 minutes (includes vegetable chopping and tomato preparation)
• Cooking Time: 2 hours (includes simmering and reducing)
• Canning Time: 60-70 minutes (depending on jar size)
• Total Time: 4 hours (makes approximately 7-9 quarts)

Step-by-Step Instructions

Step 1: Prepare the Tomatoes

Wash tomatoes thoroughly. Bring a large pot of water to boil and prepare an ice bath. Blanch tomatoes for 30-60 seconds, then transfer to ice water. The skins will slip off easily. Quarter the peeled tomatoes and simmer for 20 minutes in a large stockpot.

Step 2: Create Tomato Pulp

Pass the softened tomatoes through a food mill or fine-mesh sieve to remove seeds and create a smooth pulp. This step ensures your spaghetti sauce has the perfect consistency for canning.

Step 3: Brown the Meat and Sauté Vegetables

In a large skillet, brown your choice of ground meat until fully cooked. Add garlic, onions, celery/peppers, and mushrooms, sautéing until vegetables are tender and fragrant.

Step 4: Combine and Simmer

Mix the meat-vegetable mixture with the tomato pulp. Add salt, oregano, parsley, black pepper, and brown sugar. Bring to a boil, then reduce heat and simmer uncovered for 1-1.5 hours until thickened to your desired consistency.

Step 5: Prepare for Canning

While sauce simmers, sterilize pint or quart jars in boiling water. Keep jars hot until ready to fill.

Step 6: Fill and Seal Jars

Ladle hot sauce into hot jars, leaving 1-inch headspace. Remove air bubbles with a non-metallic utensil. Wipe rims clean with a damp cloth and apply lids and bands finger-tight.

Step 7: Process in Pressure Canner

Place jars in pressure canner with 2-3 inches of water. Process pint jars for 60 minutes and quart jars for 70 minutes at the appropriate pressure for your altitude (see notes below).

Step 8: Cool and Store

Turn off heat and let pressure drop naturally. Remove jars and cool on a towel-lined surface for 12-24 hours. Check seals, label, and store in a cool, dark place.

FAQs

Q: Can I use a water bath instead of pressure canning for this spaghetti sauce recipe?
A: No, this recipe contains meat and low-acid vegetables, requiring pressure canning for safety. Water bath canning isn’t sufficient to prevent botulism risk.

Q: How do I know if my canned sauce is safe to eat?
A: Check for proper seals (concave lids that don’t flex when pressed), no bubbling, and normal appearance/smell. When in doubt, boil the sauce for 10 minutes before tasting.

Q: Can I double this recipe?
A: Yes, but maintain proper proportions and process in batches to ensure even cooking and safe canning practices.

Q: What’s the best way to thicken the sauce?
A: Simmer longer to reduce, or add 2-3 tbsp of tomato paste during cooking. Avoid adding thickeners before canning as they can affect safety.

Q: Can I omit the sugar?
A: Yes, but the sugar helps balance the tomatoes’ acidity. Consider using a natural sweetener or increasing other seasonings to compensate.
