Ingredients Needed
Before you get started, let’s gather everything you’ll need for this recipe. Here’s the list of ingredients that form the foundation of our vegetarian potato casserole:
- Potatoes (about 6 medium-sized) – Russets or Yukon Golds work best for their creamy texture, but you can mix in some red potatoes if you prefer.
- Olive oil (2 tablespoons) – Adds richness and helps the potatoes roast beautifully.
- Yellow onion (1 medium) – A great base for flavor with a slight sweetness.
- Garlic cloves (2 cloves, minced) – Essential for that savory depth.
- Vegetable broth (1 cup) – The liquid that will help bind everything together while keeping the dish hearty.
- Heavy cream or cashew cream (1 cup) – The key ingredient for creaminess. Cashew cream is an excellent option if you want a dairy-free version.
- Shredded cheddar cheese (1 ½ cups) – For that melty, gooey texture. You can use dairy-free cheese for a vegan version.
- Parmesan cheese (½ cup) – Adds a sharp, salty bite to balance out the richness.
- Fresh thyme (2 teaspoons) – A fragrant herb that pairs well with potatoes.
- Fresh parsley (for garnish) – A burst of green color and freshness on top.
- Salt and pepper (to taste) – The basics for seasoning and bringing out all the flavors.
- Breadcrumbs (optional) – For a crunchy topping that contrasts nicely with the creamy potatoes.
Cooking Instructions
Now that you’ve got everything ready, let’s get into the step-by-step process. This recipe isn’t hard to make, but it does require a bit of time to let the flavors develop and the potatoes cook to perfection.
Step 1: Preheat The Oven
- Preheat your oven to 375°F (190°C). You want it nice and hot before the casserole goes in.
Step 2: Prepare The Potatoes
- Wash and peel your potatoes. Slice them thinly (about 1/8-inch thick). You can use a mandolin slicer to make this process quicker and ensure uniform slices.
Step 3: Sauté The Aromatics
- In a large skillet, heat olive oil over medium heat.
- Add the chopped onion and sauté until translucent, about 5 minutes. Toss in the minced garlic and cook for another minute, making sure it doesn’t burn.
Step 4: Create The Creamy Sauce
- To the skillet, pour in the vegetable broth and heavy cream (or cashew cream). Stir to combine and let it simmer for 5 minutes.
- Stir in the cheddar cheese and parmesan cheese, allowing them to melt into the sauce.
- Add in thyme, salt, and pepper to taste. Give it a good mix.
Step 5: Assemble The Casserole
- In a greased 9×13-inch baking dish, layer the thinly sliced potatoes. Pour a little of the creamy sauce over each layer of potatoes, making sure they’re evenly coated.
- Continue layering the potatoes and sauce until you’ve used everything up, finishing with a layer of sauce on top.
Step 6: Bake
- Cover the casserole with foil and bake for about 45 minutes, or until the potatoes are tender. Remove the foil and bake for an additional 10-15 minutes to allow the top to brown and become crispy.
Step 7: Garnish And Serve
- Once out of the oven, sprinkle some fresh parsley on top for a burst of color and fresh flavor.
- If you like a little extra crunch, sprinkle some breadcrumbs on top before the last few minutes of baking.
Ingredient Science Spotlight
Let’s dive into the magic happening behind the ingredients:
- Potatoes: The starchy goodness of potatoes is the base of this casserole. When baked, their starches gelatinize, giving the dish its creamy, smooth texture. Russets are particularly good because of their high starch content.
- Cheese: The cheeses create a luscious, melty sauce. Cheddar and parmesan contribute different flavors-cheddar for creaminess and mild sharpness, while parmesan adds a salty, nutty kick that elevates the whole dish.
- Heavy Cream/Cashew Cream: Creaminess is the backbone of any potato casserole, and heavy cream does this with its fat content. Cashew cream, a dairy-free alternative, offers a similar richness but with a nutty flavor.
- Herbs: Thyme provides an earthy note that complements the potatoes’ neutral flavor. Fresh parsley at the end adds a pop of freshness and lightens up the rich dish.
Expert Tips
- Make it ahead: Potato casseroles actually improve in flavor when they sit for a day or two! You can prepare the casserole a day before, refrigerate it, and then bake it when you’re ready to serve.
- For extra crispy edges: Consider adding a few tablespoons of butter to the top of the casserole before baking. This will help achieve those golden, crispy edges that everyone loves.
- Consistency matters: If you prefer a thicker casserole, use less broth and cream. For a creamier, soupier casserole, add more liquid.
- Layering tips: Try layering in some sautéed spinach, mushrooms, or other vegetables between the potatoes for added flavor and texture.
Recipe Variations
- Vegan Version: Replace the dairy with cashew cream and use plant-based cheeses to make this casserole 100% vegan. You can also switch out the butter for olive oil or vegan butter.
- Spicy Kick: Add a few diced jalapeños or a sprinkle of cayenne pepper to the cream mixture to give the casserole a bit of heat.
- Mushroom Lovers: Sauté some mushrooms with the onions and garlic, then add them to the casserole for a rich umami flavor.
- Herb Blend: Mix in other herbs like rosemary or sage to change up the flavor profile and make it a bit more fragrant and complex.
