Ingredients You’ll Need

Crafting this delectable Buttermilk Ranch Potato Gratin requires a selection of fresh, high-quality ingredients that harmonize to create its signature flavor and texture. Pay attention to the quality and preparation of each component, as they all play a vital role in the dish’s overall success. Using fresh ingredients ensures the best results. Don’t skimp on the quality of your potatoes or cheese; they are the stars of this show!

• 2 lbs baking or golden potatoes, such as Russet or Yukon Gold, thoroughly washed, unpeeled for extra flavor and texture, and sliced thinly (approximately ⅛-inch thick). Uniformly thin slicing is paramount for even cooking and a beautifully tender gratin.
• 8 slices of bacon, preferably thick-cut for a more substantial chew, chopped into ½-inch pieces. The bacon adds a crucial smoky, salty crunch and infuses the dish with its rendered fat.
• 1 head Savoy cabbage, finely shredded. This often-overlooked addition brings a wonderful subtle sweetness and tender texture when braised in the bacon grease, complementing the robust potato and ranch flavors beautifully.
• ¼ cup finely chopped fresh chives. Fresh herbs are crucial for brightening the overall flavor profile. Chives offer a delicate, oniony note without overpowering the other ingredients.
• 2 cups grated Parmesan cheese. Opt for good quality, freshly grated Parmesan for the best flavor and a superior melt. It will create that irresistible, golden-brown, gooey cheesy top.
• 1 pkt Hidden Valley Original Ranch Salad Dressing and Seasoning Mix. This is the secret ingredient that infuses the gratin with its distinctive tangy, herbaceous ranch flavor, making it truly unique.
• 2.5 cups buttermilk. The buttermilk provides a rich, creamy base for the sauce with a delightful tang, which is crucial for the gratin’s distinctive profile. It also aids in tenderizing the potato slices during baking.
• salt and pepper, to taste. Essential for seasoning throughout the layers and bringing out all the inherent flavors of the ingredients. Adjust according to your preference and the saltiness of your bacon and Parmesan.

Step-by-Step Instructions to Create Your Perfect Gratin

Follow these detailed steps carefully to achieve a perfectly cooked, golden-brown Buttermilk Ranch Potato Gratin that’s crispy on the outside and wonderfully creamy within. Precision in each step ensures a harmonious blend of flavors and textures.

1. Preheat your oven to 375 degrees F (190 degrees C). This ensures the oven is at the correct temperature for even baking from the very beginning, leading to consistent results.
2. Grease a 13″ x 9″ casserole dish thoroughly. This crucial step prevents the gratin from sticking to the dish and aids in easy serving. Set the prepared dish aside.
3. In a large mixing bowl, combine the thinly sliced potatoes, buttermilk, 1 cup of the grated Parmesan cheese, and the entire packet of Hidden Valley Ranch seasoning mix. Toss everything gently but thoroughly until the potato slices are completely coated in the creamy, flavorful mixture. This initial coating ensures every potato slice absorbs the delicious ranch and buttermilk, building flavor from the inside out. Set this bowl aside to allow the flavors to meld slightly.
4. In a large skillet or frying pan, cook the chopped bacon over medium heat. Stir occasionally until it is perfectly crispy and golden brown. This usually takes about 5-7 minutes. Once cooked, use a slotted spoon to remove the bacon pieces from the skillet and transfer them to a plate lined with paper towels to drain any excess grease. Crucially, keep the rendered bacon grease in the skillet for the next step – it’s packed with flavor!
5. To the skillet containing the reserved bacon grease, add the finely shredded Savoy cabbage. Cook the cabbage over medium heat, stirring occasionally, until it has wilted and become wonderfully tender. This typically takes approximately 5-8 minutes. Remove the skillet from the heat. Season the wilted cabbage generously with salt and pepper to taste. Now, add ¾ of the cooked crispy bacon and ¾ of the finely chopped fresh chives to the cabbage mixture. Toss everything together until well combined. Reserve the remaining ¼ of bacon and chives for garnishing the finished dish.
6. Begin assembling your gratin in the prepared casserole dish. Arrange a single, even layer of the potato slices at the bottom of the dish. For a beautiful presentation and even cooking, make sure the slices overlap slightly. Lightly sprinkle this potato layer with some of the remaining Parmesan cheese.
7. Repeat the layering process: Add another uniform layer of potato slices over the first, again ensuring they overlap. Sprinkle with more Parmesan cheese. These initial layers form the tender foundation of your gratin.
8. Next, spread the flavorful cabbage and bacon mixture evenly over the potato layers. This middle layer is where the unexpected burst of savory flavor and delightful texture comes from, making this gratin truly special.
9. Top the cabbage and bacon layer with two more layers of the remaining potato slices, making sure they are evenly distributed to complete the potato base.
10. Carefully pour about half of the remaining buttermilk mixture from the mixing bowl evenly over the last potato layer. You want just enough liquid to slightly cover the top layer of potatoes. The liquid will seep down through the layers, ensuring all the potatoes cook to tender perfection.
11. Generously sprinkle the very top layer of the gratin with the remaining Parmesan cheese. This will create a beautiful, golden-brown, and irresistibly crispy crust as it bakes.
12. Cover the casserole dish tightly with aluminum foil. Place the covered dish in the preheated oven and bake for 1 hour. Covering helps trap steam, which is essential for ensuring the potatoes become wonderfully tender without drying out.
13. After 1 hour, carefully remove the aluminum foil. Return the uncovered dish to the oven and bake for an additional 30 minutes, or until the top is beautifully golden brown, visibly bubbly, and the potatoes are fork-tender. If you notice the top browning too quickly, you can loosely cover it again with foil.
14. Once baked to perfection, remove the casserole from the oven. This next step is crucial: let it cool and rest for at least 15 minutes before serving. This resting period allows the creamy sauce to set and firm up, making it much easier to serve clean slices and preventing the gratin from becoming watery.
15. Just before serving, garnish the Buttermilk Ranch Potato Gratin with the reserved crispy bacon and fresh chives. These fresh elements add a final touch of color and flavor. Serve warm and prepare for rave reviews!

Tips for the Best Buttermilk Ranch Potato Gratin and Delicious Variations

To ensure your Buttermilk Ranch Potato Gratin is nothing short of spectacular and to explore ways to customize it to your taste, consider these expert tips and exciting variations:

Expert Tips for Success:

• Uniform Potato Slices: The absolute key to an evenly cooked gratin is uniformly thin potato slices. A mandoline slicer is highly recommended for this task, ensuring each slice is about ⅛-inch thick. If slicing by hand, take your time and aim for consistency to avoid some potatoes being undercooked and others overcooked.
• Don’t Overcrowd the Skillet for Bacon: When cooking bacon, avoid overcrowding the skillet. Cook it in batches if necessary to ensure each piece gets perfectly crispy and renders its fat efficiently, rather than steaming.
• Don’t Skip the Resting Time: Letting the gratin rest for 15 minutes after baking is crucial. This period allows the creamy sauce to set, resulting in cleaner, more stable slices when serving and preventing a watery consistency.
• Taste and Adjust Seasoning: Always taste your buttermilk-ranch mixture and the cabbage-bacon mixture before layering. Adjust salt and pepper as needed, remembering that both bacon and Parmesan cheese contribute a significant amount of salt to the dish.
• Cheese Quality Matters: While Parmesan is specified, using good quality cheese will significantly impact the flavor and melt of your gratin. Freshly grated is always superior to pre-shredded for both taste and texture.

Exciting Variations to Try:

• Spicy Kick: For those who enjoy a little heat, add a pinch of red pepper flakes to the buttermilk mixture or a dash of your favorite hot sauce.
• Herb Garden Freshness: Experiment with other fresh herbs. Dill, parsley, thyme, or a touch of finely chopped rosemary can be added alongside or in place of chives for different aromatic profiles.
• Loaded Gratin: For an even heartier dish, consider adding a layer of caramelized onions to the cabbage layer, or incorporate cooked, crumbled sausage (pork or turkey) for extra protein and flavor.
• Vegetarian Option: To make this gratin vegetarian, simply omit the bacon entirely. Instead of bacon grease, use a bit of olive oil or butter to sauté the cabbage. You can also add smoked paprika to the cabbage for a subtle smoky flavor.
• Different Cheese Blends: While Parmesan is classic, a blend of Gruyere and sharp white cheddar can offer a nuttier, tangier profile. Monterey Jack is excellent for a super gooey melt, or try smoked gouda for a deeper, more complex flavor.

Serving Suggestions and Storage Tips

This Buttermilk Ranch Potato Gratin is incredibly versatile and makes a fantastic addition to almost any meal, from casual weeknights to elaborate holiday feasts. Here are some ideas for serving it and how to best store and reheat any delicious leftovers:

Perfect Pairings:

• Classic Roast: Serve this rich gratin alongside a succulent roast chicken, a tender roasted turkey, a juicy beef tenderloin, or a savory pork loin. The creamy gratin beautifully complements the robust flavors of roasted meats.
• Grilled Delights: It’s an excellent companion to grilled steaks, smoky pork chops, or even hearty grilled vegetables, offering a creamy and comforting contrast to the charred, smoky notes.
• Holiday Feast Showstopper: This gratin is a perfect dish to feature for Thanksgiving, Christmas, or Easter dinners. Its impressive appearance and rich flavors will make it a memorable part of your holiday spread.
• Simple Weeknight Elevation: Elevate a simple weeknight meal of pan-seared chicken breasts, baked salmon, or a hearty meatloaf with this decadent side dish, transforming an ordinary dinner into something special.
• Fresh Salad Balance: To balance the richness of the gratin, serve it with a crisp, refreshing green salad dressed with a light, tangy vinaigrette. This provides a lovely counterpoint to the creamy potatoes.

Storage and Reheating:

• Refrigeration: Leftover Buttermilk Ranch Potato Gratin can be stored in an airtight container in the refrigerator for up to 3-4 days. Ensure it cools completely before refrigerating to maintain freshness.
• Freezing: While possible, freezing may slightly alter the texture of the potatoes and cream sauce upon reheating, making them a bit softer. If you choose to freeze, store portions in a freezer-safe container or tightly wrapped for up to 2 months. Thaw overnight in the refrigerator before proceeding with reheating.
• Reheating: For best results with individual portions, reheat in the microwave until warmed through. For larger amounts or to achieve a crispy top again, cover the gratin loosely with foil and reheat in an oven preheated to 350°F (175°C) until hot and bubbly, typically about 20-30 minutes. You might want to uncover it for the last 5-10 minutes to crisp up the cheese topping.
