I know, I know — it’s March. I should probably be posting grilling recipes by now, or if not at the very least St. Patrick’s Day, Easter and Mother’s Day.

But I’m still hung up on soup.

Cheeseburger Soup.

Turkey Tetrazzini Soup.

Nacho Potato Soup.

Quinoa Chowder.

Do we need more examples??

I don’t know about you, but I love soup — and it’s the perfect winter meal! It’s also one of the only ways that I get a ton of veggies in my diet and enjoy eating them.

But I also love a good thick soup that’s rich and creamy (and I think you do, too, because this Slow Cooker Garlic Parmesan Stew has been going positively nuts!). And that’s where this Vegetable Soup comes in.

I stuck with my favorite veggies in this one — carrots, peas, potatoes (I used Little Potatoes because they’re so creamy) — and I threw in a couple extra for good measure — spinach, green beans and celery. One of the best things about soup (for me, anyways) is how the flavors all meld together after such a long time cooking together, which is why I love cooking them in the slow cooker!

Soups also freeze great, so you can make a large batch and munch on it all week long, or fill some freezer containers to enjoy later when life is a little more hectic. I know I never regret throwing extra food in the freezer!

Feel free to mix up the vegetables with your favorites — mushrooms, leeks, peppers, kale, add in different spices — go nuts!

    Had some issues with the milk/cornstatch at first. I whisked them together and poured them into the soup and they immediately separated and thr cornstarch fell to the bottom of the soup in big blobs. I had to sir it every 5 minutes and eventually it started staying mixed. Next time I think I will leave out the milk altogether as the broth before was good

    • Ashley Fehr says

      I’m sorry to hear that Natasha! If the corn starch and milk are whisked together completely I’m not sure why they would separate into blobs, I haven’t had that problem before unfortunately.

  2. Stephanie says

    I used light cream with the cornstarch and the soup did not thicken. It cooked for a long time and still was thin. I thought the light cream instead of milk would help but to no avail. It was good, but I would have preferred it creamier. I don’t think cooking it longer would make a difference since I had read a previous comment and you suggested the longer cooking, but that did not help. What could be done to make this soup creamier?

  3. Meg says

    Not a fan of this at all. Tastes weird and the second step adding the milk too way longer to heat up than 1 hr. It never thickened just tast like milky broth. I truly have no idea how this is rated so high!

    • Ashley Fehr says

      Hi Meg! I’m sorry to hear that you didn’t enjoy it! All slow cookers definitely cook at a different temperature, so it may have just taken a little longer to thicken up.

    • Ashley Fehr says

      If you don’t have corn starch you can make a roux, with melted butter and flour, to thicken some milk, or you can use a heavier liquid to add creaminess, like heavy cream or evaporated milk. I hope that helps and that you enjoy it!

    We have been on a soup kick the last month. Do happy to have tried this one. Very tasty. I served it with crescent rolls stuffed with cheese. What a delight. Thanks for sharing

  5. Sladjana says

    Hi, I literally just made this soup and am afraid it went “bad” immediately after I added the milk…is it possible? It’s a little sour…just a bit…and when I turned it on high for the soup to thicken up it had slight bubbles.

    I’m not a novice cook but it dawned on me only afterwards that I’m adding a much cooler milk temperature to an already hot soup…

    Your advice is much appreciated

    • Ashley Fehr says

      I’m so sorry to hear that! It is possible, though I’ve never had a problem adding milk to a slow cooker before. If your slow cooker runs very hot or you’re using a very low fat milk, then it’s possibly it could have become too hot. Slight bubbles should be fine once you turn it to high. Curdled milk will have a funny look and texture but shouldn’t taste sour, so I would be worried about the condition of your milk.

    I have CHF and high BP so I am on a low sodium diet, can you please put the sodium count along with the calorie count.

  7. vivian says

    This soup was very good, and just what I needed to help get over a cold. I think next time I will put the spinach in later so it stays green. Thanks for a good recipe!

  8. Ashley says

    Delicious! I didn’t have the frozen veggies on hand so I used 2 zucchinis and 1 yellow pepper and 1 red pepper instead – put those in at the beginning and let it cook all day. Thanks for the recipe!

  9. ColleenB.~Texas says

    In the 70’s here today but soup still looks delicious. Like I tell my husband; it’s no different having soup when the temperatures are warm than it is having a hot casserole dish.
    For me; buying just a bag of mixed veggies makes more sense than buying individual bags of frozen veggies. I buy the largest frozen veggie bag as possible cause I do use the frozen vegetables in casserole dishes, etc.
    Thanks 4 the recipe.

    • Ashley Fehr says

      Hi Colleen, I totally agree! I can eat hot food in the Spring and I can eat soup just as well! Although we’re not having weather anywhere close to that! 🙂 You can definitely just buy a bag of mixed veggies! For some reason I prefer fresh cooked carrots to frozen but there really isn’t too much difference.

  10. Gayle @ Pumpkin 'N Spice says

    In my book, soup is needed ANY time of the year, and it’s too early for grilling still (at least here in the Midwest)! 🙂 Slow cooker soups are my favorite and I just know my husband would love this version. You can’t go wrong with a thick and creamy soup that warms you right up!

    • Ashley Fehr says

      It is absolutely FREEZING here this week — we actually had a big ice/thunderstorm the last couple days. So soup is definitely in order here! Thanks Gayle!
