Best Baked Sweet Potato Topping – Chickpea Miso Butter!

It turns out mixing butter with miso paste makes the best topping for whole roasted sweet potatoes! It’s seriously that simple – just mix ghee (or butter) with chickpea made miso paste (or regular miso paste) and use it for roasted vegetables, pasta noodles, or even sauteed dishes. It’s the best flavor enhancer! Here’s some more information:

What is chickpea miso butter, how does it taste, and where to find it?

Chickpea miso is made from brown rice and chickpeas and is typically aged for 1 to 3 months. The flavor tastes stronger than white miso yet lighter than red miso. It has the same paste-ish consistency as the regular soy miso. Chickpea made miso butter is perfect for people who can’t have soy.

Taste: Chickpea made miso paste tastes very similar to traditional soy miso. It tastes saltier than white miso but not as salty as red miso. Chickpea miso is a great substitute for people who have soy allergy.

Where to buy: I use a store bought brand called Miso Master (product link in the recipe card). This brand has miso pastes from chickpeas, brown rice, or barley. It’s perfect for people who can’t have soy products. I’ve seen them quite popular at local grocery stores and WholeFoods.

Miso butter is a flavored butter, simply by combining miso paste and butter with a fork or food processor. It was first developed by chef David Chang and now it’s widely used among recipe developers and home cooks. Use the miso butter as a topping for warm baked potatoes, sweet potatoes, and boiled noodles or as a flavor booster for sauteed dishes or even steak!

Can I use regular miso to make miso butter?

Yes. Regular miso works great to make miso butter. White miso paste works better. You can follow the 2 :1 ratio with 2 parts ghee or butter and 1 part miso paste to make miso butter.

What other dishes can you make with miso butter?

Miso butter is a great flavor booster. It tastes buttery and savory. Because it can be quite salty, depending on the dish, you might not need extra salt. Just like flavored butter, use it as a topping or spread to warm toasted sandwich bread, roasted whole sweet potatoes, or hot boiled pasta noodles. You can also use it for sauteed dishes like my Sauteed swiss chard or Sauteed asparagus. It adds great depth and umami to the dish.

How to make Whole Roasted Sweet Potatoes

Here’s a summary of steps with my best tips and tricks. (Scroll down for the complete printable recipe.)

  1. Select potatoes in similar size so they have similar bake time.
  2. Wash and scrub them to remove any dirt.
  3. Pat them dry before you bake to get crispy potato skin!
  4. Poke holes with a fork all over the potato to allow the steam to escape.
  5. Rub the skin with olive oil so it helps to get crispy and flavorful.
  6. Season with coarse sea salt so the skin will be tasty, too!
  7. Bake in a preheated oven on a parchment paper-lined baking sheet until tender.
  8. Slice them open soon out of the oven with a small paring knife. Be careful of the hot steam. If you let them sit too long, it’ll be harder to slice and fluff.

I do not recommend wrapping them in foil. Although the sweet potatoes will still cook, the skin won’t be crispy. So place them onto the baking sheet without wrapping them up!

How long to bake sweet potatoes at 400°F (204°C)

Roast the whole sweet potatoes at 400°F (204°C) for 50 minutes in the oven.

How to tell when the sweet potatoes are cooked?

Insert a knife to the thickest part of the potato. If you can easily insert it in with little to no resistance, the sweet potato is cooked through. The color will be lightly browned and the flesh will be tender and moist. You can easily fluff it with a fork.

In a hurry and don’t have 50 minutes?

If you are in a rush, slice the potatoes in half lengthwise, rub them with olive oil both inside and over the skin. Bake the sweet potatoes in the oven cut-side up for 30 minutes until the flesh is tender and the skin is lightly browned.

  • Use this time to make the miso butter by combining the ghee and the miso with a fork in a bowl.

  • If you are in a rush, slice the potatoes in half lengthwise, rub them with olive oil both inside and over the skin. Bake cut-side up for 30 minutes until the flesh is tender and the skin is lightly browned.
