These oven-roasted cabbage slices turn a basic veggie into a fancy side with hardly any work. The cuts get nice and brown in the oven, bringing out the natural sweetness while garlic adds tons of flavor to each piece. I came up with this method when hunting for low-carb options instead of regular starches, and now we make it all the time during the week.
I whipped these cabbage slices up during a night when I was trying to use up what was left in my kitchen and needed a quick veggie on the side. Nobody in my family thought cabbage could be the main attraction but those crispy edges changed their minds right away.
Ingredients
- Medium head of green cabbage: Look for one that's compact and weighty so your slices don't fall apart
- Olive oil: Helps the cabbage brown evenly and get those tasty crispy bits
- Salt: Brings out all the natural flavors and pulls moisture out for better browning
- Black pepper: Gives a gentle warmth that works well with the cabbage's sweetness
- Garlic (finely minced): Adds amazing aroma that takes this simple prep to another level
Step-by-Step Instructions
- Get Everything Hot and Ready:
- Set your oven to 400°F. This heat gives you that perfect mix of soft inside and browned outside. While your oven warms up, take off any outer leaves that look loose or discolored from your cabbage.
- Slice Your Cabbage:
- Stand the cabbage on its stem end and cut about an inch off the bottom to make a flat base. Flip the cabbage so this flat part sits on your cutting board. With a sharp knife, cut all the way through to make slices about three-quarters to one inch thick. This thickness is key so they cook right and stay in one piece.
- Add Flavor with Garlic Oil:
- Mix olive oil, salt, pepper, and minced garlic in a small bowl until everything's combined. The garlic will make the oil super tasty and soak into the cabbage while it cooks. Put your cabbage slices on a parchment-lined baking sheet in a single layer, not touching. Brush both sides with plenty of the garlic oil mix until you've used it all.
- Cook Until Golden:
- Bake in your hot oven for 20 to 22 minutes. You'll know they're done when the edges start turning golden brown and get a bit crispy. The inside should be tender when you poke it with a fork. For extra yumminess, sprinkle some flaky sea salt on top before you serve them.

Garlic makes all the difference in this dish. Though it sounds basic, the compounds in garlic totally change the cabbage as it roasts. One time I accidentally put in twice the garlic and found out it made an even stronger flavor that my garlic-crazy friends talked about for ages afterward.
Flavor Variations
The standard recipe works as a great starting point for playing around. You might add a teaspoon of smoked paprika to your oil for deeper smoky notes. For an Asian twist, brush the slices with sesame oil and throw on some sesame seeds in the last five minutes of cooking. If you like heat, mix in some red pepper flakes or drizzle hot honey on top right before serving.
Make It A Meal
Take these cabbage slices from side to main by adding protein on top. Try putting a fried egg with soft yolk that breaks into a rich sauce. For a meatless option, scatter some roasted chickpeas and drizzle tahini over everything. Meat fans can top with crumbled bacon bits or strips of grilled chicken breast laid across the roasted cabbage.
Troubleshooting Tips
When cabbage slices break apart during cooking, you've probably cut them too thin. Always go for at least three-quarters inch thickness. When buying cabbage, pick heads that feel heavy and solid rather than light and fluffy, which means the leaves aren't tight enough. If you see too much water while cooking that stops browning, just pat the cabbage dry with paper towels before adding the oil mix.

Frequently Asked Questions
- → What’s the best way to slice cabbage for roasting?
Peel off any unwanted outer leaves, cut out the stem, and then slice the cabbage into thicker pieces, about ¾-inch to 1-inch wide, so they stay intact while roasting.
- → Which seasonings work well on roasted cabbage?
Aside from the basics like salt, pepper, and garlic, try smoked paprika, chili flakes, or herbs like rosemary and thyme for extra flavor.
- → How can I stop cabbage slices from getting soggy?
Turn your oven to a high temp, like 400°F, to prevent steaming, and always reheat leftovers in the oven or air fryer instead of the microwave.
- → Can I prepare cabbage slices in advance?
You sure can! Slice the cabbage and whip up the garlic oil a couple of days ahead. Keep them in separate containers until it’s time to bake.
- → How long will roasted cabbage keep fresh?
Store it in an airtight container in the fridge for about 3-4 days. Freezing works too, but it might lose some crunch when reheated.
- → What’s the most effective way to warm up cabbage slices?
Pop them into an air fryer set at 350°F for 3-5 minutes. You can also use the oven at 300°F for 5-8 minutes for that fresh-off-the-pan crispiness.
