Slow Cooker Tomato Soup
This easy slow cooker tomato soup is made with canned tomatoes, onion, garlic, and butter (no cream) for deliciously simple flavor in every bite. Meal prep a big batch for the perfect quick lunch you can reheat in the microwave on busy days!
Equipment
- Slow cooker (4 or 5 quart)
Ingredients
- 28 ounces canned crushed tomatoes no salt added
- 1 medium yellow onion quartered
- 1 cup water
- 1 teaspoon minced garlic
- 1 tablespoon butter
- 1 teaspoon salt
- Garlic & herb croutons optional topping
Instructions
- Add all ingredients to a slow cooker or crockpot and stir to combine.
- Cover and cook on HIGH for 4 hours.
- Carefully transfer slow cooker contents to a blender. Blend on low speed for about 30 seconds, then medium speed for about 1 minute until smooth.
- Serve hot, optionally topping with croutons, or let cool and pour into airtight containers to store in the fridge or freezer.
Notes
Blending: When blending hot liquids, hold a towel (one you don't mind getting dirty) over the lid. Steam will build up inside the blender which could cause the lid to pop off, so you'll want to hold it in place. Depending on how your blender seals, some hot soup could splatter up through the middle insert of the lid, which is why we recommend using a towel!
Serving and storing: You can pour the blended soup back into the slow cooker and set it to warm if you're serving the soup later that day, or you can pour it straight into a bowl and enjoy it right away! If you're just meal prepping and want to store individual portions of soup in the fridge or freezer, we recommend letting it cool a bit in the blender, then pouring into airtight containers. For freezing individual portions of soup, we love our Souper Cubes.
Reheating: Frozen tomato soup will keep for up to 6 months and is super easy to reheat for quick and easy meals. Pop some into a microwave-safe dish and defrost, then heat for about 1 to 2 minutes or until steaming.
