There are many ways to make tomato sauce in a crockpot, with cooking times ranging from 2 to 20 hours. The desired consistency and flavour of the sauce determine how long it should be cooked for. A shorter cooking time will result in a more acidic, fresh-tomato-like sauce, while a longer cooking time will break down the acidic tomato taste and sugar for a stronger umami flavour.

Crockpot tomato sauce with fresh tomatoes
This simple crockpot tomato sauce takes little effort. It is easy to fill the crockpot with fresh tomatoes, onions, and garlic and let it simmer all day. You can even break up the process over a few days if you are short on time by cooling and refrigerating the sauce partway through and starting the cooking process again the next day.
Ingredients
- Fresh tomatoes
- Onions
- Garlic
- Carrot
- Herbs
- Wine
- Olive oil
- Salt
- Pepper
- Honey (optional)
Instructions
- Prepare your tomatoes by washing them in plain water. Cut them in half or into quarters and add them to the crockpot.
- Add the garlic, onion, carrot, and herbs.
- Drizzle with wine and olive oil.
- Cover and turn the crockpot to low. Cook for 2-4 hours, stirring occasionally.
- After the sauce has simmered and the tomatoes have released their juices and the vegetables are soft, turn off the crockpot and allow the sauce to cool.
- Run the cooled tomato sauce through a food strainer or food mill to remove skins and seeds, and to smooth out the sauce.
- Return the strained tomato sauce to the crockpot and cook down further to thicken the sauce.
- Taste the sauce and adjust the seasoning if needed. If the flavor is sharp and acidic, add a little honey and taste again.
- You can store the leftover sauce in the fridge for 2-3 days or freeze it for later.
Tips
- Cooking the tomatoes with the skins and seeds helps to thicken the sauce with the fruit's natural pectin.
- If you are using fresh herbs, add extra at the end of the cooking time.
- This homemade crockpot tomato sauce pairs perfectly with Ricotta Gnocchi, Homemade Egg Noodles, Zucchini Lasagna, spiralized veggies, spaghetti squash, and as a pizza topping.
- If you want to add meat to your sauce, it is recommended to brown it separately and then stir it into the sauce after cooking.

Simmering time
The simmering time for tomato sauce in a crockpot varies depending on the desired consistency and flavour. For a more acidic, fresh-tomato-like sauce, cooking the sauce for a shorter amount of time, such as 2 to 4 hours, is recommended. This type of sauce pairs well with hearty dishes to cut through heavier tastes. To achieve this consistency, it is important to cook the sauce on low heat with gentle bubbles surfacing and give it an occasional stir.
For a richer and more developed flavour, the sauce should be simmered for a longer period, typically between 6 to 8 hours. This longer cooking time breaks down the tomatoes, reducing the acidic taste and enhancing the umami flavour. It is common to add water or stock during extended simmering to compensate for evaporation and further enhance the flavour. Additionally, dried herbs like rosemary or thyme are recommended for long simmering times as they withstand high temperatures without losing their flavour.
Some recipes suggest even longer simmering times, ranging from 10 to 20 hours on low heat. This extended cooking time allows the sugars in the tomatoes to caramelize, resulting in a deeper flavour. It is important to note that the simmering time may vary depending on the water content of the tomatoes and the desired thickness of the sauce.
To adjust the consistency and thickness of the sauce, it can be returned to the crockpot after pureeing or straining to cook down further. This additional step ensures that the sauce reaches the desired consistency without overcooking the other ingredients.

Thickness and consistency
The thickness and consistency of your tomato sauce depend on the length of cooking time and the types of tomatoes used.
For a thicker sauce, cook your sauce for longer. A longer cooking time will reduce the water content in your sauce, making it thicker. You can cook your sauce in a crockpot for 2-4 hours, 4-6 hours, or even longer, depending on your desired thickness. If you want to speed up the reduction process, you can also simmer your sauce on a stovetop at a low temperature after cooking it in the crockpot. However, be aware that the longer you cook your sauce, the more you will need to stir it occasionally to prevent it from burning.
The type of tomatoes you use will also impact the thickness of your sauce. Tomatoes with lower water content, such as meaty, plumb, or paste tomatoes, will result in a thicker sauce. Examples of suitable paste tomatoes include Roma, San Marzano, Amish Paste, and Juliet. If you use tomatoes with higher water content, your sauce will take longer to thicken. Additionally, cooking your tomatoes with the skins and seeds helps to thicken the sauce due to the natural pectin in the fruit.
To achieve a smooth consistency, you can use a food strainer or food mill to remove the tomato skins and seeds after cooking. If you don't mind the seeds and skins, you can use an immersion hand blender to smooth out your sauce. For an even smoother sauce, you can puree the tomatoes before cooking them in the crockpot.

Spices and seasoning
Dried vs. Fresh Herbs
When cooking tomato sauce in a crockpot, it is generally recommended to use dried herbs instead of fresh ones. This is because the long cooking time can cause the flavour of fresh herbs to diminish. Dried herbs such as rosemary, thyme, oregano, and basil are excellent choices for crockpot tomato sauce. They can withstand the heat and long cooking time without losing their flavour. If you do prefer using fresh herbs, it is best to add them towards the end of the cooking process to maximise their flavour.
Basic Seasonings
Salt and pepper are essential seasonings in any tomato sauce. They enhance the natural flavour of the tomatoes and bring out the flavours of the other ingredients. Start by adding a small amount of salt, such as half a teaspoon, and then adjust to your taste preferences. Black pepper can also be added to taste, providing a subtle kick to the sauce.
Spicy Kick
If you enjoy a spicy kick to your tomato sauce, consider adding cayenne pepper. Cayenne will give your sauce a nice warmth and depth of flavour. However, use it sparingly, as a little goes a long way. You can also experiment with other spices like cinnamon, which can add a unique and unexpected twist to your sauce.
Sweetening the Sauce
To balance the acidity of the tomatoes, you can add a sweetening agent to your sauce. Brown sugar is a common choice, as it provides a rich, caramelised flavour. Alternatively, you can use honey to add a subtle sweetness and smoothen the sharp edges of the sauce.
Umami Boost
For an extra savoury boost, consider adding ingredients like balsamic vinegar, red wine, or tomato paste. These ingredients enhance the umami flavour of the sauce, making it more complex and satisfying. They also add depth and brightness to the overall flavour profile.

Storing and preservation
Refrigeration
If you plan on consuming your tomato sauce within a few days, refrigeration is a suitable option. Allow the sauce to cool completely, then transfer it to clean, airtight containers and store it in the refrigerator. Properly stored tomato sauce will generally last for 2-3 days in the fridge.
Freezing
Freezing is an excellent option for long-term storage. After your sauce has cooled, portion it into freezer-safe containers or bags. Label the containers with the date and content before placing them in the freezer. Frozen tomato sauce can last for several months and is perfect for quick weeknight meals. Simply thaw the sauce in the refrigerator or by heating it on the stovetop when you're ready to use it.
Canning
Canning is a popular method for preserving tomato sauce, especially during the peak tomato harvest season. However, it's important to note that not all crockpot tomato sauce recipes are safe for canning. If you intend to can your sauce, be sure to follow a reliable canning recipe specifically designed for that purpose. Improper canning methods can lead to food spoilage and safety hazards.
Storage Tips:
- Always use clean containers and utensils to handle and store your tomato sauce.
- When refrigerating or freezing, leave some space at the top of the container to allow for expansion.
- Label your containers with the date and content to ensure you consume the sauce while it's still at its best.
- Practice food safety by not keeping leftover sauce at room temperature for more than 2 hours. Bacteria can grow rapidly at room temperature, potentially leading to foodborne illnesses.
By following these storage and preservation guidelines, you can enjoy your delicious crockpot tomato sauce safely and conveniently whenever you crave it!
