Slow Cooker Creamy Herb Tomato Soup with Grilled Cheese Croutons

Slow Cooker Creamy Tomato Soup with Grilled Cheese Croutons. Does it even get more fall sounding than that? Here in Illinois we are getting a little autumn tease. It’s been in the lower 60’s with a cool breeze for the past few days now. I’ve opened up the house to allow the fresh cool air in. I’ve mentioned a few times now that my kitchen is switching to fall food. I’m glad Mother Nature decided to oblige and bring the cooler weather in for me. Now I just need the leaves to start changing and I’ll be golden. 

I could go on and on about how much I love this weather. Summer and I have never truly gotten along. It’s mostly because of my hair. I have this crazy hair that just never cooperates with the humidity.  I am not a fan of sweating. At all. I long for cooler weather where I can curl up on the couch with a blanket, hot coffee, and look out the window to see trees bursting with orange, gold, maroon, and yellow. I love that it’s finally time for soups, stews, and yummy casseroles. I’m sure you all are just as excited as I am to spend some more time in the kitchen and not have to worry about how hot it makes the house when the oven is on. 

The past few weeks I’ve been dreaming of tomato soup. I love a good creamy tomato soup. While digging through old recipes, I found this one. The basis of this recipe is from a Taste Of Home Cooking Class I took a few years back. That was so much fun! I need to look into if they still do these, because I learned so much in just those few short hours. Of course, I added some different things here and there over the years to make it as flavorful as can be. And I switched to almond milk instead of heavy cream that I used to use to make it more WeightWatchers and calorie friendly. If you want to splurge on your calories or don’t give a you know what about calories, add the heavy whipping cream instead! Both ways are beautifully delicious. 

In this post, I will also show you how to make grilled cheese croutons, it’s basically just glorified grilled cheese cut into tiny squares. However, there’s a plot twist. Read along and you’ll see. 

When I first started cooking, the word “roux” frightened me. It’s just a word. Don’t let it scare you. I promise it’s a lot easier than it sounds. Just follow along with the directions and it’ll be just perfect for you to enjoy. 

Now let’s get cookin’!

Creamy Herb Tomato Soup

Grab your crockpot and add vegetable broth, crushed tomatoes, onions, garlic, and carrots.

Time for some spice: add in parsley, oregano, basil, salt, and pepper.  Put the cover on the pot, set to low, and go about your day. Come back in about 7-8 hours (until the veggies are nice and soft)

Flash forward: It’s been 7-8 hours. ha!

Now let’s get to this roux. Try to place your crock pot as close as you can to your stove top. It’ll make the process easier while pouring some of the tomato mix into the pot.

In a pot over low heat add your butter and olive oil.

Now, take your flour and slowly pour in while whisking. Whisk constantly for about five minutes, until its a glue-like yellowish brown paste.

Slowly pour in one cup of the tomato mixture from the crockpot while whisking. Whisk together until thouroughly mixed.

Now slowly pour in 4 more cups of the tomato mixture while whisking together, and whisk until smooth, then add the thickened soup back into the slow cooker with the remaining tomato mixture.

Now add in the parmesan cheese. I LOVE PARMESAN CHEESE! 


and the almond milk! Mix all together and continue to cook on low for another half hour.


Now during this half hour, while you’re waiting for this soup to be done…. You can either go relax on the couch OR make some grilled cheese croutons! 

Grilled Cheese Croutons

Here’s the plot twist: Butter & Light Butter can be higher in points and calories. I use the diner trick and I use Light Mayo instead of butter on grilled cheese for the “buttered” side of the bread. Diners use real mayo, but light mayo tastes just as good. Feel free to use butter or whatever you would normally use to make a grilled cheese. 


Okay so grab some day old bread, I personally LOVE sourdough bread. You can use whatever you want. Like I said, this is a glorified grilled cheese sandwich cut into tiny squares, but they are PERFECT to top off your soup with. When you make this your friends and family with think you’re genius and you spent SO much time on grilled cheese croutons! I know Eric thought I was a dang prodigy when I put the bowls of soup on the table for dinner the other night. 

Back to the recipe, spread the mayo on the side of the bread that you’ll use to grill.

In a lightly sprayed skillet lay down the mayo side of the bread and top with cheddar.

Top with the other slice of bread and grill for 2-4 minutes until golden brown.

Flip and grill for another 2-4 minutes until golden brown.

Now set out and let it cool for about 10 minutes.

Now cut the sandwich into strips



and then into squares




Now grab some fresh basil, chop it up. This is completely optional, but I LOVE the taste of fresh basil in this soup. It really just completes the meal, and it makes it look pretty. 

Creamy Herb Tomato Soup


Top your soup with your grilled cheese croutons and some basil, and you’re good to go! Serve Immediately.

    Gosh, your pictures are just so lovely! I love tomato soup and your little croutons are making this one really dazzle. I wish I could take such gorgeous pictures. You should teach an online class. I would sign up! I’m really anxious to try this with almond milk. Sometimes I just make really light soups and then pour in a tablespoon of half and half right into my bowl, just to get that creamy texture.

    • Erin, haha! It is ALL about the lighting. I usually always photograph between 10 am and 2 pm because those are the times when the sunlight isn’t coming directly through my kitchen window! I also have just read thousands of blogs about food photography. The only real advice I can give is keep at it eventually you just start to learn what props work best what colors compliment each other best etc! For almost every photo I take there’s at least 10 more at different angles and positions. I’ve been dabbling a lot with unsweetened almond milk lately because it’s so much lower in points, to my surprise it’s worked very well as a substitute! I’ve never even thought to add a bit of cream afterwards to thicken it up. Can we just live next door to each other so we can bounce ideas off each other all the time? Xo!

  2. Could you replace almond milk with FF Milk? Not sure if you need the thicker texture

  4. IS garlic missed in the ingredients?
    It mentions garlic earlier in the recipe.

  5. Hello!
    I might be misreading this but does the recipe have garlic in it? At one point it says add the garlic but it’s not in the ingredients I don’t believe.
    Thank you!

  6. How many servings does this make? Sorry if you already put that but can’t find it! I am
    Making for the football Sunday and want to make sure I have enough for our guests! Thanks!
