Get ready to revolutionize your pasta nights!
## Why Use a Slow Cooker for Tomato Sauce?
Before we dive into the recipes, let’s talk about why a slow cooker is the perfect tool for making tomato sauce:
* **Hands-Off Cooking:** This is the biggest advantage! Simply toss all the ingredients into the slow cooker, set it, and forget it. No constant stirring or babysitting required.
* **Deep Flavor Development:** The long, slow cooking process allows the flavors to meld and deepen in a way that’s impossible to achieve with quicker methods. The tomatoes break down slowly, releasing their natural sweetness and creating a smooth, velvety texture.
* **Reduced Risk of Burning:** Unlike stovetop cooking, where the sauce can easily scorch if left unattended, the slow cooker provides even, gentle heat, minimizing the risk of burning.
* **Free Up Your Stovetop:** Perfect for busy weeknights or when you need to cook multiple dishes simultaneously.
* **Great for Batch Cooking:** Make a large batch of sauce and freeze it for future meals. It’s a fantastic way to have homemade sauce on hand whenever you need it.
## Choosing Your Tomatoes
The quality of your tomatoes will significantly impact the flavor of your sauce. Here’s a breakdown of the best options:
* **Fresh Tomatoes (When in Season):** Ripe, in-season tomatoes are the gold standard. Roma or San Marzano varieties are particularly well-suited for sauce-making due to their meaty texture and low water content. Peel and seed them before adding them to the slow cooker. *See below for a detailed guide to peeling and seeding tomatoes.*
* **Canned Whole Peeled Tomatoes:** These are a convenient and reliable option year-round. San Marzano tomatoes are generally considered the best quality. Look for tomatoes packed in juice, not puree.
* **Canned Crushed Tomatoes:** While convenient, crushed tomatoes often contain seeds and skins, which can affect the texture of the sauce. If using crushed tomatoes, consider running the finished sauce through a food mill or blender for a smoother consistency.
* **Canned Tomato Puree:** Tomato puree can be used, but it often lacks the depth of flavor of whole or crushed tomatoes. If using puree, consider adding a tablespoon or two of tomato paste to boost the flavor.
**Important Note:** Avoid using diced tomatoes, as they tend to retain their shape and don’t break down as well during slow cooking.
## Essential Ingredients for Slow Cooker Tomato Sauce
Beyond tomatoes, several other ingredients are crucial for creating a flavorful and balanced sauce:
* **Aromatics:** Onions, garlic, carrots, and celery (mirepoix) form the foundation of a classic tomato sauce. Sautéing these vegetables before adding them to the slow cooker enhances their flavor and adds depth to the sauce. However, you can add them directly to the slow cooker for a truly hands-off approach. Keep in mind that the flavor will be slightly different.
* **Herbs:** Fresh herbs like basil, oregano, thyme, and rosemary add brightness and complexity. Add them towards the end of the cooking time to preserve their flavor. Dried herbs can be added at the beginning.
* **Olive Oil:** Use a good quality extra virgin olive oil for richness and flavor.
* **Salt and Pepper:** Season generously to bring out the natural sweetness of the tomatoes and balance the acidity.
* **Sugar (Optional):** A pinch of sugar can help to balance the acidity of the tomatoes, especially if they are not fully ripe. Start with a small amount and adjust to taste.
* **Red Wine (Optional):** A splash of red wine adds depth and complexity to the sauce. Use a dry red wine, such as Chianti or Cabernet Sauvignon.
* **Tomato Paste:** A tablespoon or two of tomato paste adds concentrated tomato flavor and richness. Sautéing the tomato paste before adding it to the slow cooker caramelizes the sugars and enhances its flavor.
* **Balsamic Vinegar (Optional):** A touch of balsamic vinegar adds a sweet and tangy note to the sauce.

This recipe is a great starting point. Feel free to customize it with your favorite ingredients and flavors.
**Yields:** About 6 cups
**Prep time:** 15 minutes
**Cook time:** 6-8 hours on low or 3-4 hours on high
**Ingredients:**
* 2 (28-ounce) cans whole peeled tomatoes, preferably San Marzano
* 1 large onion, chopped
* 4 cloves garlic, minced
* 2 carrots, chopped
* 2 celery stalks, chopped
* 1/4 cup extra virgin olive oil
* 1/4 cup chopped fresh basil

**Equipment:**
* Slow cooker

**Instructions:**
1. **(Optional) Sauté the Vegetables:** Heat the olive oil in a large skillet over medium heat. Add the onion, carrots, and celery and cook until softened, about 5-7 minutes. Add the garlic and cook for another minute until fragrant. Add the tomato paste and cook for 1-2 minutes, stirring constantly, until it starts to caramelize.
2. **Combine Ingredients in Slow Cooker:** Transfer the sautéed vegetables (if using) to the slow cooker. Add the canned tomatoes (crush them with your hands as you add them), basil, oregano, salt, pepper, sugar (if using), and red wine (if using).
3. **Cook:** Cover and cook on low for 6-8 hours or on high for 3-4 hours. The sauce should be thick and the tomatoes should be very soft.
4. **Blend (Optional):** For a smoother sauce, use an immersion blender to blend the sauce directly in the slow cooker. Alternatively, carefully transfer the sauce to a regular blender and blend until smooth. Be careful when blending hot liquids.
5. **Adjust Seasoning:** Taste the sauce and adjust the seasoning as needed. Add more salt, pepper, or sugar to taste.
6. **Serve:** Serve the tomato sauce over your favorite pasta, use it as a base for pizza, or incorporate it into other recipes.
## Variations on the Basic Recipe
Once you’ve mastered the basic slow cooker tomato sauce recipe, you can start experimenting with different variations:
* **Spicy Arrabbiata Sauce:** Add 1-2 teaspoons of red pepper flakes to the slow cooker along with the other ingredients.
* **Balsamic Tomato Sauce:** Add 2-3 tablespoons of balsamic vinegar to the slow cooker during the last hour of cooking.
* **Mushroom Tomato Sauce:** Sauté sliced mushrooms along with the onions and garlic. Add them to the slow cooker with the other ingredients.
* **Meat Sauce:** Brown ground beef, Italian sausage, or other meat in a skillet before adding it to the slow cooker. Drain off any excess grease.
* **Vegetarian Tomato Sauce:** Add other vegetables like bell peppers, zucchini, or eggplant to the slow cooker along with the other ingredients.
* **Roasted Garlic Tomato Sauce:** Roast a whole head of garlic in the oven until soft and caramelized. Squeeze the roasted garlic cloves into the slow cooker with the other ingredients.
* **Herby Tomato Sauce:** Increase the amount of fresh herbs, such as basil, oregano, thyme, and rosemary.
## Tips for Perfect Slow Cooker Tomato Sauce
* **Don’t Overfill the Slow Cooker:** Overfilling the slow cooker can prevent the sauce from cooking properly and may cause it to boil over.
* **Adjust Cooking Time as Needed:** Slow cookers vary in temperature, so you may need to adjust the cooking time accordingly. The sauce is done when the tomatoes are very soft and the sauce has thickened.
* **Stir Occasionally:** While not essential, stirring the sauce occasionally during cooking can help to prevent sticking and ensure even cooking.
* **Let the Sauce Cool Completely Before Freezing:** Allow the sauce to cool completely before transferring it to freezer-safe containers or bags. Leave some headspace in the containers to allow for expansion during freezing.
* **Use a Food Mill for a Seedless Sauce:** If you prefer a completely seedless sauce, run the cooked sauce through a food mill before serving.
* **Sautéing Enhances Flavor:** While you can skip the sautéing step, taking the time to sauté the vegetables and tomato paste will significantly enhance the flavor of the sauce.
* **Add Cheese Rinds (Optional):** For a richer, umami flavor, add a Parmesan cheese rind to the slow cooker while the sauce simmers. Remove the rind before serving.
## How to Peel and Seed Tomatoes
If you’re using fresh tomatoes, peeling and seeding them will result in a smoother sauce.
**Instructions:**
1. **Score the Tomatoes:** Use a paring knife to score an “X” on the bottom of each tomato.
2. **Blanch the Tomatoes:** Bring a large pot of water to a boil. Gently drop the tomatoes into the boiling water for 30-60 seconds, or until the skins start to peel away from the scored area.
3. **Ice Bath:** Immediately transfer the tomatoes to a bowl of ice water to stop the cooking process.
4. **Peel the Tomatoes:** Use your fingers or a paring knife to peel the skins off the tomatoes. The skins should slip off easily.
5. **Seed the Tomatoes:** Cut the tomatoes in half horizontally. Gently squeeze out the seeds and watery pulp. You can also use a small spoon to remove the seeds.
