Ingredients
Scale
- 4 tablespoons butter, divided
- 1 teaspoon garlic, minced
- 1 small yellow onion, halved and thinly sliced
- 1/3 cup all-purpose flour or gluten-free flour
- 1 1/2 cups dairy-free unsweetened, unflavored creamer or half & half
- 1/2 cup chicken broth, more to thin
- 1 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
- 1 1/2 cups Gruyére cheese, freshly shredded, divided
- 1 cup Monterey Jack cheese, freshly shredded, divided
- 1/2 cup parmesan cheese, grated
- 3–4 medium sweet potatoes (yams), sliced 1/8 inch thick*
Instructions
- Preheat: Preheat oven to 375 degrees F.
- Cook Onions: Bring a large cast iron skillet to a medium-high heat and add 2 tablespoons butter to melt. Swirl to coat pan. Add garlic and onions; move around pan until softened – about 2-3 minutes. Remove onions and set aside on a plate.
- Make Sauce: Keeping the hot skillet at a medium high heat, add the remaining 2 tablespoons of butter to melt. Whisk in the flour to create a roux or paste. Whisking consistently, gradually pour in the creamer about 1/4 cup at a time. Continue adding and whisking until all of the creamer is incorporated. Add broth the same way and continue whisking. Simmer gently to thicken a little bit and then add the salt, pepper, and onions back to the pan; stir to combine. If you feel you need to thin it out a little, simply add additional splashes of chicken broth until your desired consistency is reached.
- Add Cheese: Remove from heat and add half the gruyere cheese, half the monterey jack cheese, and all of the parmesan cheese. Stir to melt.
- Layer Potatoes: In a 9×13 baking dish, spread about 1 cup of the cheese sauce on the bottom of the pan. Add the sweet potatoes to the dish, stacking them in 3 rows down the pan. Cover the tops of the potato slices in the rest of the cheese sauce. Sprinkle the rest of the gruyere cheese and monterey jack cheese on top (feel free to add extra cheese on top, if desired).
- Bake: Cover with aluminum foil and bake in the preheated oven for 40 minutes. Remove the foil and return to the oven to bake, uncovered, for 10 more minutes.
- Rest & Serve: Remove from the oven and let rest for about 10-15 minutes and then serve!
Notes
- *Sweet Potatoes: we technically used yams in this recipe because typically people use the word “sweet potato” when they actually mean yams. Yams are larger and have a deeper orange color.
- Creamer: highly recommend using NutPods Original unsweetened/unflavored creamer for a slightly lighter sauce, but you can also use half & half.
- Gluten Free: simply use gluten-free flour instead of all-purpose flour.
