These caramelized miso-maple leeks take an often-overlooked veggie and turn it into a stunning side with deep, complex flavors. The sweet-savory combo of maple and miso creates a delicious glaze that clings to each tender bite.
I came up with this method during a cold-weather cooking session when my local market had tons of leeks. What began as a simple side has now become my go-to dish at gatherings, with everyone asking me how I make it before they leave.
Essential Components
- 6 small leeks: Keep the roots on to help them stay together while the soft parts soak up all the tasty sauce
- Olive oil: Helps brown the leeks first, building the base flavors
- Flaky sea salt and fresh cracked pepper: Brings out the natural sweetness in the leeks
- Light miso paste: Adds that can't-put-your-finger-on-it umami taste and smooth texture
- Hot water: Helps the miso mix smoothly into the sauce
- Chicken stock: Makes the braising liquid that softens the leeks perfectly
- Soy sauce: Gives extra depth and saltiness to balance the sweet notes
- Maple syrup: Adds a rich sweetness that regular sugar just can't match
- Toasted sesame oil: A tiny bit adds wonderful nutty background flavor
- Mirin: Brings a light tang and natural sweetness
- Thinly sliced garlic cloves: Fills the sauce with amazing aroma
- Butter: Makes the sauce velvety and extra rich
- Chili flakes: Not required but really nice for a touch of heat against the richness
- Lemon zest: Sprinkled at the end to add bright citrus notes that make everything pop
Cooking Method
- Get Ready:
- Turn your oven to 425°F and get everything out. This high heat will make the edges nice and brown while keeping the insides soft.
- Fix Up the Leeks:
- Cut off the dark green tops and pull away any tough outer leaves. Cut each leek down the middle but don't cut through the root end so they stay in one piece. Wash them well under cold water to get all the dirt out from between the layers. Dry them completely with paper towels so they'll brown properly.
- Mix the Miso:
- Stir light miso with hot water in a small bowl until it's totally smooth. Add the water bit by bit until you can pour it easily so it'll spread evenly in the pan. This stops the miso from clumping up in your dish.
- Brown the Leeks:
- Get a big oven-safe pan really hot. Add olive oil and put the leeks cut-side down carefully. Let them cook without moving for 3-4 minutes until they're nice and brown. Sprinkle with salt, pepper, and chili flakes if you want. Flip them over and cook another 2-3 minutes on the other side.
- Make the Sauce:
- Pour in half the chicken stock which will bubble and loosen all the tasty brown bits. Drizzle the miso mixture around the sides of the pan rather than right on top of the leeks. Add soy sauce, maple syrup, sesame oil, and mirin all around the pan.
- Finish Cooking:
- Scatter garlic slices throughout and drop small pieces of butter around the leeks. Pour in just enough stock to come halfway up the sides of the leeks. Let it come to a boil on the stove, then put the whole pan in the hot oven. Cook for 20-25 minutes until the leeks are fork-tender and the sauce has thickened into a nice glaze.

The miso is really what makes this dish special. I tried making it once when I'd run out and couldn't believe how flat it tasted without that fermented goodness. My husband noticed right away something was missing, which shows just how important this ingredient is to getting that wow factor.
Finding Perfect Leeks
Go for small or medium leeks with bright green tops and clean white sections. Smaller ones tend to cook more evenly and taste more tender than big ones. Stay away from any with yellowish leaves or too much dirt as this means they're old. When you prep them, keep that root end on so the layers don't fall apart while cooking and they look prettier on the plate.
Prep In Advance
This dish actually tastes even better the next day once the flavors have had time to mingle. You can cook the whole thing up to three days ahead and keep it in the fridge in a sealed container. When you want to eat it, warm it in a 350°F oven with foil on top for about 15 minutes, then take the foil off for the last 5 minutes to get some of that nice browning back. Don't throw away any leftover sauce it's amazing drizzled over rice or other veggies.
What To Serve With It
These flavor-packed leeks go great with miso-glazed salmon, roasted chicken, or grilled tofu. For a complete meal, serve them with some steamed short-grain rice to soak up all that yummy sauce and a simple cucumber salad with rice vinegar and sesame seeds for freshness and crunch. Cold sake or a crisp white wine like Grüner Veltliner works perfectly to cut through the richness while matching the sweet-savory balance.
