It is soon to be Valentine’s Day and what could be more romantic than to share a bowl of pasta? To make your day easier all you have to do is put your ingredients in a slow cooker. That leaves you the whole day to explore and enjoy each other’s company. When you arrive home a big pot of delicious Slow Cooker Marinara Sauce is waiting for you.
You can think past the pasta too and make pizza, soup, mussels, braised meats, or poached eggs with this delicious versatile sauce. You can leave it naturally vegan or change it up to how you enjoy it. A good sauce is the start of many recipes. Also, try our amazing Instant Pot Spaghetti Sauce for a quick and easy meal.
Start with great ingredients and you will in turn, end up with a great sauce. I used our own canned tomatoes but there are increasingly better products out there now. I am in love with San Marzano tomatoes, some brands are better than other. For the pureed tomatoes you can buy them already like that or pop some great quality tomatoes in a blender. So easy and it makes a difference.
You can enjoy this sauce all year long in all of you favorite dishes!! But for right now think Valentine’s Day!! Hugs and kisses!!
