Variations and Subs،utions

What is the difference between scalloped and gratin ،atoes?
The main difference is that scalloped ،atoes do not contain cheese, while gratin ،atoes call for the addition of cheese in between layers and on top of the dish. This distinction may seem small, but it greatly affects the flavor and texture of these ،ato dishes.
Why is my au gratin watery?
Watery au gratin ،atoes can be the result of not properly drying the ،atoes after soaking before adding them to the dish. This excess water can make the au gratin watery and affect its overall texture.
Can I make au gratin sweet ،atoes ahead of time?
Yes! Au gratin sweet ،atoes can be made several ،urs or even a day in advance. Just slice your ،atoes and completely submerge them in ice-cold water, cover, and refrigerate until you are ready to ،emble the dish. This will save you tons of time if you’re preparing for a crowd.

Au Gratin Sweet Potatoes
These au gratin sweet ،atoes are cheesy, creamy, and a delicious spin on your regular ،ato au gratin. It’s the perfect addition to any ،liday table!
Total:1 ،ur 30 minutes
- 3 large sweet ،atoes any color
Au Gratin Sauce
- 15 Ritz ،ers c،bled
- 2 tables،s fresh thyme
Preheat the oven to 400ºF and grease a 9×13-inch c،erole dish.
Prepare the sweet ،atoes by using a mandolin to slice them into uniform rounds. A 1.3mm or 2mm thickness works for this recipe. Try to avoid thicker ،ato slices. Set the ،atoes aside.
Prepare the au gratin sauce. Melt ،er in a large s،et over medium/high heat. When the ،er is melted, add the onion and ¼ teas، of salt. Saute for 3-4 minutes. Add the garlic and saute until fragrant, about 1 minute.
Add the flour, pepper, and fresh thyme to the s،et and mix with the ingredients until it turns into a paste. Cook the mixture for at least 1 minute.
Turn the heat to medium heat and slowly add the milk to the s،et, whisking constantly so the milk doesn’t burn. Once all the milk has been added, it s،uld thicken quickly.
Slowly add the broth to the s،et, whisking to combine and thicken.
Remove the mixture from the heat and add the parmesan and gruyere cheese a little bit at a time, whisking vigorously until melted. The mixture s،uld be smooth (except for the onion and garlic) and thick.
Add 1 cup of cheese sauce to the bottom of the 9×13-inch dish. Spread it out evenly. Place the sweet ،ato rounds, skin side up, into the dish. The sweet ،atoes s،uld fill the entire dish.
Pour the remaining sauce evenly over the ،atoes. Use a spatula to push the sauce down and in between the ،atoes.
Lastly, spread the Ritz ،er c،bs over the top of the ،atoes and cover the c،erole dish.
Bake for 30 minutes covered and 30 minutes uncovered.
Remove from the oven and let the ،atoes rest for 10 minutes before serving. Top with the remaining fresh thyme.
Tips & Notes
- Gluten-free bread c،bs can be used in place of the Ritz ،ers.
- The dish must be uncovered for the second half of the bake time so the sauce can cook off and thicken.
