Ingredients
3 pounds ripe fresh garden tomatoes, cored and chopped
The star of the recipe, fresh tomatoes provide the soup’s vibrant color, natural sweetness, acidity, and rich garden-fresh flavor. Choose ripe, juicy tomatoes for the best results. There is no need to peel them—the skins soften during slow cooking and contribute texture and flavor.
4 cups low-sodium chicken broth
Chicken broth creates the savory liquid base and helps mellow the acidity of the tomatoes. Low-sodium broth gives you better control over the final seasoning. Vegetable broth can easily be substituted if preferred.
1 medium yellow onion, finely chopped
The yellow onion adds savory sweetness and depth. As it slowly cooks with the tomatoes, it becomes tender and almost melts into the broth.
2 teaspoons kosher salt
Salt brings all the flavors together and helps the tomatoes taste fuller and more balanced. Start with the recommended amount and adjust toward the end according to the saltiness of your broth and tomatoes.
8 ounces wide egg noodles
Wide egg noodles turn the tomato broth into a satisfying meal. Their soft, silky texture is perfect with the chunky tomatoes and makes this simple soup especially comforting.
How to Make Slow Cooker Amish Tomato Noodle Soup
1. Prepare the tomatoes
Rinse the tomatoes thoroughly under cool running water. Remove the cores and chop the tomatoes into chunky pieces.
You do not need to peel the tomatoes. The skins will soften as they cook, saving you extra preparation time.
2. Fill the slow cooker
Add the chopped tomatoes, chicken broth, onion, and kosher salt to a 5- to 6-quart slow cooker.
Stir gently until everything is evenly distributed and the tomatoes are mostly surrounded by broth.
3. Slow cook the tomato base
Cover the slow cooker and cook on LOW for 6–7 hours or HIGH for 3–4 hours.
The tomatoes should become very soft, and the onions should be completely tender. The broth will develop a deeper red color and a rich, savory aroma.
4. Crush the tomatoes
Once the tomato mixture has finished cooking, use a wooden spoon or potato masher to gently break down some of the tomatoes.
Don’t puree everything. Leaving small tomato pieces gives the finished soup a wonderfully rustic texture.
Taste the broth and add a little additional salt if necessary.
5. Add the egg noodles
Turn the slow cooker to HIGH if it isn’t already.
Stir the dry egg noodles into the hot tomato broth, gently pressing them down so they are mostly submerged.
6. Cook until the noodles are tender
Cover and cook on HIGH for 15–25 minutes, stirring once about halfway through.
Keep an eye on the noodles because cooking time can vary depending on their size and brand. You want them tender and silky without becoming mushy.
7. Taste and serve
Give the soup a final stir. Taste and adjust the salt if needed.
Ladle the hot tomato noodle soup into bowls and serve immediately. Fresh or dried herbs make a simple garnish if desired.
Why Everyone Loves This Tomato Noodle Soup
It uses only 5 main ingredients. You don’t need a pantry full of spices or specialty ingredients to make a flavorful pot of soup.
The slow cooker does the work. Once the tomato base is assembled, you can let it simmer while you handle the rest of your day.
Fresh tomatoes make it special. Ripe summer tomatoes give the broth a flavor that canned tomatoes simply can’t duplicate when your garden is overflowing.
It’s wonderfully comforting. Soft egg noodles and savory tomato broth make this soup feel like an old-fashioned homemade meal.
It’s perfect for sharing. A large slow cooker makes it especially convenient for summer potlucks, family dinners, church suppers, and casual gatherings.
Pro Tips for the Best Slow Cooker Tomato Soup
– Use the ripest tomatoes you can find. Tomatoes that are deeply colored, fragrant, and juicy will give you the sweetest, most flavorful broth.
– Don’t over-crush the tomatoes. A few small chunks provide rustic texture and make the soup feel homemade.
– Add the noodles near the end. Egg noodles cook quickly, so adding them at the beginning can leave you with overly soft noodles.
– Taste before adding more salt. Broth can vary considerably in sodium, so adjust gradually.
– Balance very acidic tomatoes. If your tomatoes are particularly tart, a small pinch of sugar can round out the flavor.
– For a smoother soup, briefly use an immersion blender on the tomato base before adding the noodles. Leave some tomato pieces intact if you enjoy a chunky texture.
– For the best leftovers, cook the noodles separately if you know you’ll be storing the soup. They continue absorbing liquid and can become very soft overnight.
Easy Variations
Although the basic recipe is intentionally simple, there are several ways to customize your Amish-style tomato noodle soup.
For an herbier flavor, add a little dried basil or oregano while the tomato base cooks.
For a creamy variation, stir in ½ to ¾ cup heavy cream or half-and-half after the noodles are fully cooked. Warm gently before serving.
To make the soup more substantial, add cooked shredded chicken or browned ground beef toward the end of cooking.
A bay leaf can also add subtle depth to the tomato broth. Remove it before adding the noodles.
What to Serve with Tomato Noodle Soup
This soup is delicious on its own, but a few simple sides can turn it into a complete meal.
Serve bowls of slow cooker tomato noodle soup with warm, crusty bread for dipping. Soft dinner rolls are equally good for soaking up the flavorful broth.
For the ultimate comfort-food combination, serve it alongside a grilled cheese sandwich. The crisp, buttery bread and melted cheese are a natural match for the bright tomato broth.
For a lighter summer meal, pair it with a cucumber and sweet onion salad tossed with a simple vinaigrette.
At a potluck, set out small bowls of grated Parmesan, shredded cheddar, and chopped fresh herbs so everyone can customize their serving.
How to Store Leftovers
Allow leftover soup to cool promptly, then transfer it to shallow containers and refrigerate within 2 hours.
Store refrigerated leftovers for 3–4 days. When reheating, heat the portion you plan to eat until steaming hot, reaching 165°F (74°C).
Because the egg noodles continue absorbing the tomato broth as the soup sits, they can become softer over time. For the best texture when preparing the soup ahead, consider cooking the noodles separately and adding them to individual servings.
If freezing, freeze the tomato soup base without the noodles. Thaw and reheat the tomato portion, then add freshly cooked noodles when serving.
