This slow cooker roasted fall vegetables recipe makes it easy to load your table with hearty flavor-packed veggies with very little effort. Toss everything in the slow cooker for a colorful side that celebrates harvest season and keeps prep time to a minimum. It is my go-to way to get a healthy side dish with almost no hands-on work when life gets busy.

This has been my saving grace during holiday gatherings when my oven is already full. I started making this the year I hosted Thanksgiving for twelve and it is now a tradition everyone requests.

Ingredients

  • Baby potatoes: choose waxy varieties like Yukon Gold for creamy texture and slice them evenly for even cooking
  • Carrots: look for firm and bright carrots with no cracks or soft spots they add natural sweetness and pair well with the other veggies
  • Green beans: fresh pintos work best avoid limp or overripe ones for the best crunch
  • Brussels sprouts: pick tight compact sprouts for the best flavor and slice larger ones in half for tenderness
  • Olive oil: use a good quality extra virgin olive oil for rich flavor and to help the seasonings stick
  • Seasoning: use your favorite blend I often use a mix of garlic powder onion powder dried thyme and smoked paprika for cozy warmth

Step-by-Step Instructions

Prep the Vegetables:
Wash and dry all the vegetables. Cut potatoes into halves or quarters based on size. Peel and chop carrots to about two inch pieces. Trim ends off green beans and Brussels sprouts. The size of your cuts matters for even cooking and tender results.
Toss with Oil and Seasonings:
Add all the vegetables to the slow cooker. Drizzle evenly with olive oil. Sprinkle your seasoning blend over everything. Toss well so that every piece is coated. This helps guarantee your veggies are flavorful in every bite.
Slow Cook to Perfection:
Cover and set your slow cooker on high for four to five hours or low for eight to ten hours. Check for doneness by piercing potatoes and carrots with a fork. They should be tender but not falling apart. If using a round slow cooker stir gently once or twice for even cooking.
Serve and Enjoy:
Once ready transfer the roasted vegetables to a platter. Taste and add an extra sprinkle of seasoning or a drizzle of olive oil if you want. Serve warm as a side to any meal or even as a hearty vegetarian main dish.

Green beans are my secret star in this mix their crunch makes every bite pop. One year my youngest niece turned up her nose at Brussels sprouts until she tried them slow cooked and now she always asks for seconds.

Storage Tips

Store leftover roasted vegetables in an airtight container in the fridge for up to four days. They heat up well in the microwave or in a skillet over medium heat. You can also freeze portions for up to two months just allow to thaw in the fridge overnight for best texture.

Ingredient Substitutions

Root vegetables like parsnips or sweet potatoes work beautifully here for extra color and sweetness. If you do not have Brussels sprouts try chunks of butternut squash. I sometimes toss in thick slices of red onion or bell peppers for a bit more flair.

Recipe FAQs

→ Can I use frozen vegetables?

Fresh vegetables are best for optimal texture, but thawed frozen veggies can work if excess water is drained before cooking.

→ What type of seasoning tastes best?

Classic Italian seasoning, garlic powder, or a blend of herbs like rosemary and thyme complement fall vegetables beautifully.

→ Should I stir the vegetables while cooking?

If using a traditional slow cooker, stirring once or twice during cooking helps ensure even roasting and prevents sticking.

→ How do I avoid soggy vegetables?

Select root veggies or varieties with low water content, and avoid overcrowding the cooker to maintain firmer texture.

→ Can leftovers be refrigerated?

Yes, store cooled vegetables in an airtight container in the fridge for up to 4 days. They reheat well for meal prep.

A 6-quart or larger slow cooker is ideal to accommodate this quantity, allowing the vegetables to cook evenly.
