Grocery List & Substitutions

This easy sweet potato casserole is made with simple ingredients, many you probably already have on hand. If there is a substitution for an ingredient, you’ll find it below:

• Sweet potatoes: try to find uniform sweet potatoes so they bake up evenly and are easier to slice!
• Butter: salted or unsalted butter will work, if using salted butter you may not need to add as much kosher salt to seasoning. I don’t recommend using margarine as it can be to watery. Vegan butter can be used to make this dish vegan.
• Garlic cloves: fresh garlic works best in this recipe, or use jarred minced garlic. Add as much garlic as you’d like!
• Shallot: I like a shallot for a more mild taste but any kind of onion will work, use yellow onion, red onion, or white onion. Omit if desired.
• Heavy cream: I like the richness of the heavy whipping cream. Or use half and half, whole milk, or 2%milk (cashew cream could be substituted if needed to make this dish vegan).
• Kosher salt: any type of salt will work, Celtic salt or Himalayan salt is best. I also like to top the finished dish with some flaky sea salt.
• Fresh thyme: I like a mix of fresh thyme and oregano, any fresh herbs will work! Dried herbs can be used if needed.
• Parmesan: I highly recommend a fresh grated parmesan cheese, it’s not overly heavy but adds a nice flavor. Gruyere cheese, Colby jack, Monterey jack, or cheddar cheese could be a substitute, you could also substitute a vegan cheese.

Recipe FAQs

I don’t not recommend freezing the scalloped potatoes either uncooked or cooked. These are best enjoyed fresh, freezing will change the texture of the potatoes and could cause the sauce to break.

How long do I bake scalloped potatoes?

If sliced thinly and evenly, these will cook from in 50-60 minutes. Adjust timing as needed until desired consistency is reached. The thickness of the potatoes will impact baking time.

Do you soak sweet potatoes in water before cooking?

No, you do not need to soak these potatoes before baking. When making fries it can be helpful to soak the potatoes prior to baking or frying to pull out some of the starch. But that is not needed when baking these potatoes.

It is recommended to peel the sweet potatoes for these scalloped potatoes so you get a smooth, creamy texture. But you can leave unpeeled if desired.
