1-First Step: Prep the oven and pan Start by heating your oven to 400°F. This temperature gives the potatoes enough heat to brown while still cooking them through gently. Choose a baking dish or roasting pan that fits the potato rounds in a mostly single layer. A snug fit helps the broth and butter mixture stay in contact with the potatoes, which is part of what gives them that tender, melting texture. If you are cooking for a mixed group, this step is easy to adapt. Leave the skins on for extra fiber and a more rustic look, or peel the potatoes if you want a softer finish. Either way works well for this sweet potatoes recipe.

2-Second Step: Slice the sweet potatoes evenly Wash the sweet potatoes well, then peel them if you want. Cut them into 1-inch-thick rounds. Try to keep the slices as even as possible so they roast at the same pace. If some pieces are much thinner than others, they can dry out before the thicker ones are done. Uniform sizing matters most in recipes like roasted sweet potatoes because the texture is what makes them shine. Thick rounds give you that contrast between a crisp exterior and a soft center. If your potatoes are very wide, you can cut some rounds in half after slicing, as long as the pieces are still similar in size.

3-Third Step: Mix the flavor base In a small bowl or measuring cup, whisk together the melted butter, olive oil, kosher salt, and black pepper. This mixture coats the sweet potatoes and helps them roast evenly. The butter brings richness, while the olive oil keeps the edges from drying out. Salt and pepper may seem basic, but they are what make the flavor pop. Place the potato rounds in a large bowl and pour the butter mixture over them. Toss gently until every piece is coated. The potatoes should look glossy, not drenched. If you are making a lower-calorie version, you can reduce the butter slightly and add a bit more broth later in the pan.

4-Fourth Step: Arrange with rosemary and garlic Spread the coated sweet potatoes in the baking dish. Scatter the smashed garlic cloves around them, then sprinkle the chopped rosemary over the top. As the dish roasts, the garlic softens and becomes sweet and mellow, while the rosemary perfumes the whole pan. That scent is one of the best parts of making this dish. Pour the broth into the bottom of the baking dish, taking care not to wash off too much of the coating on top. The broth helps create steam so the centers turn tender while the tops brown. This is the trick behind that melting sweet potatoes soft center texture people love.

5-Fifth Step: Roast until tender Cover the dish tightly with foil and roast for about 25 minutes. The foil traps steam and helps start the softening process. After 25 minutes, remove the foil, baste the potatoes with the pan juices, and return the dish to the oven uncovered. Roast for another 20 to 25 minutes, or until the potatoes are fork-tender and the tops are golden. If you want more melting sweet potatoes crispy edges, leave the dish uncovered for the final part of roasting. You can also spoon some of the butter broth mixture over the tops once or twice during baking. That small extra step gives the slices a deeper glaze and a richer finish.

6-Final Step: Serve warm with the pan juices When the potatoes are done, let them rest for a few minutes so the glaze settles. Then transfer them carefully to a serving platter and spoon the garlicky rosemary pan juices over the top. The finished dish should have browned edges, tender centers, and a rich smell that makes everyone head straight to the table. Serve them hot as a side dish with chicken, fish, holiday roasts, or even a simple grain bowl. They also work well for students, busy parents, and working professionals because the leftovers reheat nicely.
