What You’ll Need:

Ingredients for Slow Cooker Roasted Fall Vegetables including carrots, sweet potatoes, butternut squash, parsnips, onion, garlic, and herbs

For this Slow Cooker Roasted Fall Vegetables recipe, gather the following reliable ingredients:

  • 4 cups peeled and chopped carrots (about 4 medium carrots)
  • 3 cups peeled and cubed sweet potatoes (2 medium sweet potatoes)
  • 3 cups diced butternut squash (about 1 small squash)
  • 2 cups chopped parsnips
  • 1 large onion, quartered
  • 4 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 teaspoon dried rosemary
  • 1 teaspoon dried thyme
  • Salt and black pepper to taste
  • 1/2 teaspoon smoked paprika (optional for a smoky touch)

No worries if you don’t have parsnips on hand—I often swap them for more carrots or even turnips in my Slow Cooker Roasted Fall Vegetables. These vegetables are usually easy to find in your regular grocery aisle through the fall season.

Budget-wise, this fall vegetable recipe keeps costs reasonable because all the ingredients are basics you can buy fresh or even frozen. For a shortcut, you can purchase pre-cut vegetables, just rinse and pat dry so they don’t get too watery in the slow cooker. If you’re using fresh garlic, it gives that dish a nice warm note, but garlic powder is an okay substitute if that’s what you have.

If you end up with leftovers, store them in an airtight container in the fridge for up to 3 days. They reheat beautifully, making your Slow Cooker Roasted Fall Vegetables even easier to enjoy for lunch the next day.

This Slow Cooker Roasted Fall Vegetables always gets a little personality tweak from me—I like adding an extra pinch of rosemary or a squeeze of lemon right before serving to brighten everything up.

Let’s Make It Together:

Here’s how to bring your Slow Cooker Roasted Fall Vegetables to life step-by-step:

  1. Prep your veggies: Peel and chop the carrots, sweet potatoes, butternut squash, and parsnips into similar-sized pieces for even cooking. Quarter the onion and mince the garlic.
  2. Dress veggies with oil and spices: In a large bowl, toss all your chopped vegetables with olive oil, rosemary, thyme, smoked paprika (if using), salt, pepper, and minced garlic. This step coats everything well, so flavors infuse during slow cooker cooking.
  3. Load the slow cooker: Transfer the seasoned vegetables into your slow cooker. Spread them evenly to help them cook uniformly.
  4. Cook on low for 6-8 hours: Set your slow cooker to low and let it do the work. This slow cooker roasted vegetables method allows the root vegetables to soften and develop that lovely roasted flavor without any standing over a hot oven.
  5. Check for doneness: About 6 hours in, start checking the veggies with a fork. They should be tender but not mushy. Don’t worry if they look a little moist—that’s normal in slow cooker cooking. If you’d like them a bit more caramelized, you can spread them on a baking sheet and roast in your oven at 425°F for 10 minutes.

From start to finish, this Slow Cooker Roasted Fall Vegetables take about 8 hours, making it perfect for tossing in the morning and having dinner ready by evening.

While the vegetables cook, you can get other dinner prep sorted or set your table. One of my favorite things is how this slow cooker roasted vegetables recipe lets you multitask easily without rushing.

A kitchen tip: Don’t overcrowd the slow cooker or layer the veggies too thick because that can slow down the roasting effect. If you have a smaller slow cooker, halve the recipe or cook in batches.

If you want to mix things up, add some chopped Brussels sprouts or beets for an autumn vegetable medley that tastes hearty and fresh.

Your Questions Answered:

Can I make this Slow Cooker Roasted Fall Vegetables ahead of time?
Absolutely. You can prep and toss the veggies in the seasoning the night before, refrigerate them in the slow cooker insert or a bowl, and then start slow cooker cooking the next day. Leftovers also reheat well and taste great warmed up.

What’s a good substitute for butternut squash in this recipe?
If you don’t have butternut squash, pumpkin, acorn squash, or even sweet potatoes can work. I’ve tried using kabocha squash for a richer flavor. It all blends nicely with the roasting spices.

How do I adjust this Slow Cooker Roasted Fall Vegetables for more people?
Double or triple the ingredients but be sure to use a larger slow cooker to avoid overcrowding. You can also spread the veggies into two separate slow cookers or cook in batches.

Can I add fresh herbs instead of dried?
Yes, but add fresh herbs like rosemary or thyme during the last 30 minutes of slow cooker cooking to keep their bright flavor from fading.

Is it okay to use frozen vegetables?
Yes, though fresh veggies will have a better texture and flavor when roasted. If you use frozen, reduce the cooking time slightly since frozen vegetables don’t need as long to soften.

What if I want a crispier finish?
After slow cooker cooking, spread the veggies on a baking sheet and roast at a high temperature for 10 minutes. This adds a nice crisp edge similar to oven-roasted root vegetables. Here’s a tip from Love and Lemons’ roasted root vegetables.

Can I include other vegetables?
Definitely. Add sliced mushrooms, Brussels sprouts, or diced zucchini for variety. Just remember denser vegetables like carrots and potatoes need longer cooking times.

This Slow Cooker Roasted Fall Vegetables is forgiving, so tweak it to your family’s tastes. When I posted this to my kitchen group, many cooks suggested adding sage or a splash of apple cider vinegar for extra fall warmth.
