FAQs & Tips

What vegetables should you use?

I encourage you to make this recipe work for you. Use the vegetables listed in the recipe box as a guide. Substitute your favorite veggies but keep in mind that some are better than others when it comes to slow cooking. Stick to sturdy or root vegetables. Don’t have a red onion? Use a white or yellow onion instead.

What type of potatoes should you use?

What you see in the pictures is red potatoes. Feel free to use your preferred potato or even sweet potato. Don’t like butternut squash? Omit them and use all potatoes instead. Or make this low-carb with only green vegetables.

Will the butternut squash & potatoes turn to mush?

They will if you overcook them which is very easy to do. For avoid this, cut your butternut squash and potatoes into larger chunks than you normally would. This will help them to hold their shape while cooking. Also make sure they’re uniform in shape & size so they cook evenly together. Leaving the skin on the potatoes will also help.

How do you store leftovers?

Store leftover crockpot harvest vegetables in the refrigerator for up to 3 days. 

What size slow cooker did you use?

I used a 3.5 quart slow cooker.

  1. My vegetable were in for 6 hours and were still not done. I filled the vegetables to the top of the crockpot. Is that to much?

    1. I’m sorry to hear this. It’s possible you added to much food. You slow cooker could also have a low heating element. Unfortunately, that’s one of the down falls of slow cooking. Every appliance heats differently. I hope you give the recipe another try!

    Hi. What brand slow cooker do you use. I’m nervous about mushy vegetables.

    1. Hi Michelle, I used a 3.5-quart oval Crockpot.

      That’s a valid concern, it’s very easy to overcook vegetables. If you have the time, I would check it after a couple of hours. If it’s cooking quickly, turn it to WARM or even turn it off. If you turn off the slow cooker & keep the lid on, it will still continue to cook.
      Let me know if you need more assistance!

        I have time. Would you recommend on low or the high? It wouldn’t matter is I wasn’t bringing for a friend’s dinner.

          1. This came out well. And was enjoyed by all.

            Would you have directions for roasting? Oven temp and cook length?
            Thanks!
            Michelle
