    This hearty marinara sauce is Whole30 approved. San Marzano tomatoes are mildly acidic, allowing us to take a sugar-free approach. Our authentic marinara sauce is made with common pantry ingredients and comes together in 1-hour!

    Most store-bought sauces are expensive and sub-par in flavor. Our hearty marinara sauce is the best because we use Italian San Marzano tomatoes.

    San Marzano are canned tomatoes that are rich, tender, and mildly acidic. I crush the whole tomatoes in my hand over a big bowl leaving a chunky texture. Tomato sauce shouldn't be pureed in the blender, in my opinion.

    Rao's is the best marinara sauce you can buy, and the only supermarket option I would recommend. In fact, this is a copycat recipe yielding a bright red, and rich-tasting sauce.

    How to make marinara sauce better

    • Onions and garlic add layers of flavor to any dish, especially marinara sauce.
    • If you like it spicy, add red pepper flakes or Calabrian chili paste.
    • Don't forget the fresh basil. I like hand-torn basil leaves added at the end of the cooking process.

    Ingredients

    Stock your pantry with these marinara sauce ingredients to whip up an easy marinara sauce from scratch.

    San Marzano Tomatoes - These Italian tomatoes make a hearty marinara sauce with their tender texture, rich flavor, and mild acidity.

    See recipe card for quantities.

    Ingredients for this recipe.

    How to make hearty marinara sauce

    Crushing whole tomatoes.

    Step 1: Crush whole tomatoes in their juices over a large bowl. The texture should look and feel like chunky salsa.

    Step 4: Season with torn basil leaves, oregano, salt, and pepper.

    Swaps and Substitutions

    • Canned tomatoes make a great marinara sauce alternative. Drain the juice and puree in a blender. Reduce the sauce until it reaches a thicker consistency.
    • Make it AIP. Saute beets and carrots with olive oil and simmer with water and balsamic vinegar. 
    • Marinara sauce without onions and garlic. These two ingredients are not friendly to some people's stomachs.
    • What spices can I add to marinara sauce? Red pepper flakes, Italian Seasoning, Parsley, Oregano, and Basil.

    How to serve marinara sauce

    Hearty tomato sauce shows up in many different Italian recipes.

    • Sandwiches - A chicken parmesan sandwich is perfect for dipping with a marinara sauce.
    • Pasta - Lasagna, Pappardelle, Linguini, and Ravioli all love to be tossed in this red sauce in Southern Italy.
    • Pizza - Reducing will thicken a marinara sauce by removing water for a thicker consistency for spreading on pizza.
    • Meatballs with marinara sauce - One of my favorite appetizers is Italian meatballs.

    Storage and Reheating Instructions

    How long does marinara sauce last in the fridge?

    The homemade marinara sauce will last 7-10 days under refrigeration. If it tastes fermented or has noticeable mold growth, throw it out. I like to store my marinara sauce in these Wreck glass jars.

    Can you freeze marinara sauce?

    You can freeze leftover tomato sauce. Place into freezer bags or air-tight containers and freeze for up to 1 year. When you want to use it again, take it out of the freezer and let it thaw for 2-3 hours.

    Can you can hearty marinara sauce?

    Properly canned, the marinara sauce has a shelf life of 1 year if stored in a cool dark place. A basement is an optimal place to store canned tomatoes and vegetables since it's the coolest part of your house.

    Chef Tips

    • San Marzano canned tomatoes are imported from Italy and make a hearty pasta sauce.
    • Simmer over low heat to prevent the sauce from scorching.
    • Cook for a minimum of 1-hour for a robust marinara sauce. Quick tomato sauce recipes lack flavor.
    • Crush tomatoes by hand for the best texture. Use whole San Marzano tomatoes for this recipe.
    • Hand-torn basil leaves are added at the END of the cooking process to perfume the sauce with that amazing basil smell and flavor.

    Frequently Asked Questions

    Can you use marinara sauce for pizza?

    The answer is yes! Since both sauces use the same ingredients, the marinara makes a great spread for pizzas. Pizza sauce is thicker and more concentrated than marinara sauce.

    What goes in marinara sauce?

    A tomato sauce that consists of tomatoes, garlic, onions, and herbs. Variations include capers, chili flakes, and white wine.

    Can you have marinara sauce on the keto diet?

    It depends, many store-bought sauces contain added sugar, making them non-compliant. Homemade sugar-free marinara sauce is your best bet.

    Which store-bought marinara sauce is the best?

    Rao's marinara sauce is hands down the best option. This recipe is a copycat version of Rao's, and it's sugar-free.
