Ingredients and Variations
- MEAT: Use lean ground beef for the best flavor, or add in ground sausage or pork for a bit of variation.
- TOMATOES: There are two types of tomatoes called for in this recipe; whole canned tomatoes and diced tomatoes. If fewer large chunks of tomatoes is desired, simply use a can of diced tomatoes instead of whole tomatoes.
- MUSHROOMS: While this recipe calls for canned mushrooms, fresh are always delicious! Other veggies to add are bell peppers, carrots or even zucchini.

What to Serve With Spaghetti Sauce
This spaghetti sauce is delicious with any long pasta such as spaghetti, but linguini and fettuccini would be delicious too. Or use a shorter pasta such as rigatoni, penne or ziti.

Tips To Cook Pasta For Spaghetti Sauce
- Boil water with a tablespoon salt added. Once water is rolling, add spaghetti and stir immediately to avoid noodles sticking together.
- Always check for doneness about 1 minute earlier than the recommended cook time to make sure it does not overcook. Spaghetti is best al dente – cooked but still firm!
- Drain, and reserve the pasta water. Do not rinse the pasta and do not add oil either, as this will inhibit the sauce from sticking to the pasta. Garnish with freshly cracked pepper, parsley, and parmesan cheese if desired.
