How to Make A Comforting Twist on a Classic
Step 1: Prep Your Ingredients
Start by peeling and thinly slicing your russet potatoes. This part is a little meditative, and the thinner the slices, the creamier and more melt-in-your-mouth your casserole will be. Dice your onion and mince the garlic, setting everything out so the process flows seamlessly.
Step 2: Sauté Onion and Garlic
Melt the butter in a skillet over medium heat, letting it foam slightly before you add the diced onions. Cook for two to three minutes, stirring often, until they’re soft and translucent. Toss in the minced garlic, letting it sizzle for just a minute until fragrant. The aroma alone is reason enough to love A Comforting Twist on a Classic!
Step 3: Mix the Creamy Sauce
In a large bowl, whisk together the sour cream, milk, salt, black pepper, and cayenne pepper if you’re using it. This sauce forms the luscious backbone of the casserole, ensuring every forkful of potato is perfectly seasoned and deliciously moist.
Step 4: Combine Everything Together
Now stir the sautéed onions and garlic into your creamy sauce, mixing well. Add the thinly sliced potatoes and gently toss until every piece is coated. Finally, fold in 1 1/2 cups of the shredded Pepper Jack cheese, reserving the rest for the topping. This is the moment where all those bold flavors start building together for A Comforting Twist on a Classic.
Step 5: Assemble and Bake
Spread the potato mixture evenly in a greased 9×13-inch baking dish. Top with the remaining Pepper Jack and optional cheddar cheese for an extra golden, cheesy crust. Cover the pan with foil and bake at 375°F (190°C) for 45 minutes, then remove the foil and bake for another 15–20 minutes, until the cheese is bubbly and the potatoes are fork-tender.
Step 6: Rest and Serve
Once it’s out of the oven, let your Spicy Pepper Jack Potato Casserole sit for about 10 minutes so the layers can set and flavors meld. Just before presenting, sprinkle on green onions or parsley for a fresh pop of color. Now, you have A Comforting Twist on a Classic that’s ready to impress!
