Slow Cooker Roasted Vegetables Recipe (1)

I love cooking delicious dinners for my family, but by the time I’ve made the main dish, the side dish is usually an afterthought.

I love roasting vegetables in the oven because it is quick, easy and they come out perfectly tender.

I knew I wasn’t going to have a lot of time later in the day to make dinner, so I whipped these Slow Cooker Roasted Vegetables up in a few minutes, let my slow cooker do the work for me and we had a tasty side dish ready by dinnertime!

How to Roast Vegetables in the Oven:

If you prefer to roast your vegetables in the oven or didn’t put these veggies in your slow cooker early enough in the day to be ready by dinner time you CAN make cook them in the oven.

Prepare the vegetables according to the recipe instructions, then spread in an even layer on a baking sheet sprayed with nonstick cooking spray rather than placing them in the slow cooker.

Cook at 425 degrees F. for 25-30 minutes, or until vegetables are tender and start to brown.

How to Roast Vegetables in the Slow Cooker:

These Slow Cooker Roasted Vegetables might be my new favorite side dish because they are so easy to make.

Slow Cooker Roasted Vegetables Recipe (2)

Start by cutting your vegetables into bite-sized pieces. If you dice your vegetables, they will be cut too small.

You also want to be sure to cut your zucchini into larger pieces as it will cook the fastest.

Slow Cooker Roasted Vegetables Recipe (3)

Pour all of the cut vegetables into a gallon-sized resealable bag, pour olive oil over the vegetables and sprinkle with Italian seasoning.

Seal the bag then shake to coat all the vegetables in oil and seasoning.

Pour the bag of seasoned vegetables into a slow cooker sprayed with nonstick cooking spray.

Notes

We love serving these roasted veggies with our7-Up Grilled Chicken,Maple Dijon Glazed Chickenor ourEasy Marinated Pork Chops.

This crock pot recipe is one of my favorite slow cooker recipes because it is an easy recipe and has a bunch of veggies. You can serve up a large bowl, or a small bowl and you will still be sure to have an array of vegetables on your plate. It is hard to find simple recipes that include root veggies, but this recipe is a great way to make that happen.

You can also mix and match your favorite vegetables, and replace them for the ones in this recipe. Some might want to add red bell pepper, brussels sprouts, butternut squash, or even sweet potatoes. Any of these options are a great way to create your favorite vegetable recipe into a mixture of vegetables.Another way to personalize this recipe is to add fresh herbs. During the warmer months I like to include fresh rosemary from my faden.

    I will give this a try. Thanks and have a great evening.

  2. valerie says:

    Have you ever used frozen veggies? And have you ever used sweet potatoes? Wondering if those might work...

  3. Mrs. Amanda Spear says:

    Looks Delicious!!

  4. Camille says:

    I have used frozen veggies for other recipes . . . they definitely don't need to cook as long because they tend to get mushy. And sweet potatoes totally work! They are so good! :)

  5. cindy orozco says:

    Since I dont have a Slow~Cooker at the moment, Can I do these in the oven? If so what temp & how long??

  6. foss says:

    Oven is best! 425 for 50 minutes. Make sure there is extra virgin olive oil. The tops should get a little charred giving it an even better taste

  7. Beth Hammer says:

    Sweet potatoes cook pretty rapidly compared to white potatoes. If you use both, cut the sweet potatoes in larger pieces so they don't mash all up.

  8. Beth Hammer says:

    In the oven I usually use a baking sheet, cover the sheet with parchment paper, add vegetables then cook. Spreading them out makes them all cook more evenly.

  9. Leslie says:

    do these veggies heat up well in the crock pot?

  10. Cyd says:

    This recipe is cooked in the slow cooker (or a crock pot). I'm not sure if you are referring to when you can reheat them. We reheat any leftovers in the microwave.

  11. Bridgette Barnett says:

    Super delicious. Made them for my family and my husband said this goes beyond restaurant quality- it's like personal chef quality! This one's a keeper.

  12. Bridgette Barnett says:

  13. Cyd says:

    Yah! Thanks Bridgette for letting us know. We are so glad you liked the veggies! Have a terrific week.

  14. Jen says:

    I'm going to make this as my Christmas dinner side dish and wondered what size slow cooker you use to make it. I'm going to purchase a new slow cooker, so should I buy a 4 quart or 6 quart size for this recipe?

  15. Momma Cyd says:

    Go with the 6 quart.

  16. Denise says:

    How many people does this recipe feed?

  17. Momma Cyd says:

    If you scroll down to the recipe card it says it will serve 8 people.

Why are my vegetables still hard in slow cooker? ›

Not enough liquid: Slow cookers rely on moist heat to soften food. If you don't have enough liquid in the pot, the carrots won't cook evenly and may stay tough. Aim for at least a cup or two of liquid, enough to reach about a third of the way up on the ingredients.

What happens if you don't brown meat before slow cooker? ›
