Longhorn Steakhouse Sweet Potato Recipe (Copycat with Cinnamon Butter)

Craving that warm, sweet-and-savory loaded sweet potato from Longhorn Steakhouse? This copycat Longhorn Steakhouse Sweet Potato recipe gives you the soft, fluffy interior, the caramelized skin, and — most importantly — the signature cinnamon butter and cinnamon sugar topping that makes the restaurant version so addictive. Best of all, you can make the whole thing in your air fryer in well under an hour.

If you’ve ever ordered the loaded sweet potato as a side with your steak, you already know the magic is in the topping. The potato itself is simply baked until tender, but it arrives at the table with a little dish of whipped cinnamon honey butter and a sprinkle of cinnamon sugar that melts right into the flesh. This version recreates that experience exactly — no restaurant reservation required.

This recipe is part of my growing collection of copycat Longhorn Steakhouse recipes, so if you’re building a steakhouse-style dinner at home, you’re in the right place.

Why You’ll Love This Recipe

• It actually tastes like Longhorn. The cinnamon honey butter and cinnamon sugar are the whole point — and they’re both here, not skipped.
• Fast in the air fryer. No 60-minute oven bake. The air fryer gives you crisp skin and a fluffy center in about 35–45 minutes.
• Just a handful of ingredients. Sweet potatoes, butter, a little sugar and cinnamon, and a touch of honey. That’s it.
• Easy to make “loaded.” Want the marshmallow-topped restaurant version? There’s a simple variation below.
• Great for steakhouse night. Serve it alongside other Longhorn copycats for a full restaurant spread at home.

Ingredients You’ll Need

For the sweet potatoes:

• Sweet potatoes – Choose medium potatoes that are roughly the same size so they cook evenly. Garnet or jewel sweet potatoes give you that deep orange, naturally sweet flesh.
• Olive oil – Rubbed into the skin for a crisp, slightly caramelized exterior.
• Sea salt – Or kosher salt, to season the skin.

For the cinnamon honey butter (the Longhorn secret):

• Salted butter – Softened to room temperature so it whips up smooth.
• Powdered sugar – Dissolves into the butter for a silky, sweet finish.
• Honey – Adds that subtle floral sweetness the restaurant version has.
• Ground cinnamon – Warm and cozy; don’t skip it.

For the cinnamon sugar topping:

• Granulated sugar and ground cinnamon – Stirred together and sprinkled over the top so it melts into the hot potato.

How To Make Longhorn Steakhouse Sweet Potatoes

Step One: Prep the potatoes. Scrub the sweet potatoes under cold water and dry them completely. Rub each one all over with olive oil, sprinkle with sea salt, and poke a few holes with a fork so steam can escape and they don’t burst.

Step Two: Air fry. Place the sweet potatoes in a single layer in the air fryer basket — don’t crowd them. Air fry at 400°F for 35–45 minutes, until a fork slides in easily. Larger potatoes will take closer to 45 minutes.

Step Three: Make the cinnamon honey butter. While the potatoes cook, whip the softened butter with the powdered sugar, honey, and cinnamon until light and creamy. Set aside at room temperature.

Step Four: Mix the cinnamon sugar. Stir together the granulated sugar and cinnamon in a small bowl.

Step Five: Assemble. When the potatoes are fork-tender, let them rest 5 minutes. Slice each one open lengthwise, fluff the flesh gently with a fork, add a generous spoonful of cinnamon honey butter, and finish with a sprinkle of cinnamon sugar. Serve warm.

Tips for the Best Copycat Sweet Potatoes

• Match the size. Potatoes of similar size finish at the same time, so you’re not pulling one out while another is still firm.
• Don’t skip the oil. A thin coat of olive oil is what gives you that lightly crisp, caramelized skin instead of a soft, steamed one.
• Let them rest. Five minutes of rest lets the inside finish softening and makes them easier to split.
• Soften the butter fully. Cold butter won’t whip smooth — leave it out for 30–45 minutes first.
• Don’t crowd the basket. Air needs to circulate. Cook in batches if your air fryer is small.

Make It “Loaded” (The Restaurant Version)

Want the full loaded sweet potato Longhorn serves? After slicing and buttering the hot potatoes, top each one with a small handful of mini marshmallows and return them to the air fryer at 350°F for 2–3 minutes, just until the marshmallows puff and turn golden. Finish with the cinnamon sugar. It’s part dessert, part side dish — and absolutely worth it.

How To Store, Freeze, and Reheat

Reheating: Reheat in the air fryer at 350°F for 5–7 minutes to bring back the crisp skin, or microwave for 1–2 minutes if you’re in a hurry. Add fresh cinnamon butter after reheating. Join Our Facebook Page and group for all your Air Fryer Recipes and Tips!

Storing: Keep cooled leftover sweet potatoes in an airtight container in the fridge for 3–4 days. Store the cinnamon butter separately so you can add it fresh when reheating.

Freezing: Wrap cooked, cooled potatoes in foil, then place in a freezer-safe bag. They’ll keep for up to 3 months.

Frequently Asked Questions

What makes Longhorn’s sweet potato different from a regular baked one? It’s the topping. The potato itself is a simple baked sweet potato, but it’s served with a whipped cinnamon honey butter and a sprinkle of cinnamon sugar — that combination is what gives it the signature sweet, warm, dessert-like flavor.

Can I make this in a regular oven instead of the air fryer? Yes. Bake the oiled, salted, pricked sweet potatoes at 400°F for 45–55 minutes, or until fork-tender, then add the cinnamon butter and cinnamon sugar the same way.

Do I need to wrap the sweet potatoes in foil? No. Skipping the foil and coating the skin in olive oil gives you a crispier, more caramelized exterior, which is closer to the restaurant version.

How do I know when they’re done? A fork or knife should slide into the thickest part with no resistance, and the potato will give easily when gently squeezed.

Can I make the cinnamon butter ahead? Absolutely. Whip it up to 1 week ahead and store it covered in the fridge. Let it come back to room temperature before serving so it’s soft and spreadable.
