The Health Benefits of Brussels Sprouts

Beyond their delightful flavor in this au gratin, Brussels sprouts are a powerhouse of nutrition, offering a wide array of health benefits. These miniature cabbages are rich in essential nutrients and potent antioxidants, making them an excellent addition to any diet. They are an outstanding source of Vitamin K, crucial for blood clotting and bone health, and Vitamin C, a vital antioxidant that supports immune function and collagen production. Additionally, Brussels sprouts provide significant amounts of folate, manganese, and Vitamin B6, all contributing to overall well-being.

The antioxidants present in Brussels sprouts, particularly Vitamin C, play a key role in reducing inflammation throughout the body’s tissues and cells. Given that chronic inflammation is linked to numerous serious health conditions, including various forms of cancer, incorporating anti-inflammatory foods like Brussels sprouts into your diet is a smart choice for long-term health. Furthermore, Brussels sprouts are remarkably high in dietary fiber, which is essential for healthy digestion. Fiber helps regulate bowel movements, promotes gut health, and can also contribute to lower cholesterol levels, thereby reducing the risk of heart disease.

The Secret Ingredient: Paisley Farm Dilled Brussels Sprouts

When we emphasized the simplicity of this recipe, we truly meant it! What could be easier than twisting the lid off a jar to unleash a burst of flavor? This recipe cleverly utilizes the exceptional Dilled Brussels Sprouts from Paisley Farm. Their distinctive taste is a culinary revelation, pairing exquisitely with the Havarti cream sauce. The combination of dill and Havarti cheese is, quite simply, a match made in heaven for your taste buds, creating a depth of flavor that elevates this gratin to gourmet status with minimal effort.

Paisley Farm Dilled Brussels Sprouts are best described as “dilled to perfection.” Each sprout offers the ideal crunch, making them a fantastic, tangy snack for lovers of both dill pickles and Brussels sprouts. These versatile sprouts can be served in place of ordinary pickles in almost any setting. Add them to an elegant charcuterie board for a unique touch, toss them into a vibrant salad for an extra zing, or even use them as a sophisticated drink garnish. And yes, they are so delicious, you might just find yourself eating them straight out of the jar, as we often do! As an added bonus, they are dairy-free, gluten-free, and vegan, making them an inclusive and thoughtful choice for entertaining guests with various dietary preferences.

Effortless Excellence: The Easy Brussels Sprouts and Potatoes Au Gratin Recipe

Creating this magnificent au gratin dish requires surprisingly little effort, allowing you to achieve impressive results without complicated techniques. The beauty of this recipe lies in its straightforward layering process, followed by a simple bake in the oven. There’s no need for elaborate sauces, roux, or fussy preparations. All the ingredients meld together as they bake, creating a harmonious blend of flavors and textures that comes out perfectly creamy and golden every single time.

Essential Ingredients for Your Creamy Potato and Brussels Sprouts Gratin

For a complete list of ingredients and detailed step-by-step instructions, please refer to the full printable recipe card located at the bottom of this post.

• Paisley Farm Dilled Brussels Sprouts: These are the star! You’ll need about 16 ounces (a little over half of a 24-ounce jar), thoroughly drained and sliced in half. The pre-dilled sprouts infuse the dish with a wonderful, tangy flavor that complements the Havarti beautifully.
• Red Potatoes: Approximately one pound, washed and thinly sliced. We prefer to leave the skins on for added nutrients and rustic charm, but feel free to peel them if you prefer a smoother texture. Thin slices are key for even cooking.
• Havarti Cheese: One and a half cups, freshly shredded. Havarti is known for its mild, buttery, and slightly acidic flavor, which melts into an incredibly smooth and creamy sauce, making it perfect for au gratin.
• Heavy Cream: Three-quarters of a cup. This provides the luxurious, rich base for our cheese sauce. While you can substitute half-and-half or whole milk to lighten the recipe, be aware that the final dish may not be quite as decadent and creamy.
• Salt and Pepper: To taste. These essential seasonings enhance all the other flavors in the dish.
• Fresh Dill: One teaspoon, minced. Fresh dill brings a vibrant, aromatic freshness that perfectly complements the Havarti and dilled Brussels sprouts. If fresh dill isn’t available, you can substitute with about 1/3 teaspoon of dried dill, though fresh is highly recommended for the best flavor.

Step-by-Step: How to Make This Delectable Brussels Sprouts & Potato Bake

Achieving this mouthwatering Brussels Sprouts and Potato Bake is simpler than you might imagine. Follow these easy steps for a perfect dish every time:

Preheat your oven to 400 degrees F. Lightly spray a 4-quart casserole dish with olive oil to prevent sticking and ensure easy cleanup. Set the prepared dish aside.

Drop the thinly sliced potatoes into a pan of generously salted boiling water. Cook them until they are fork-tender, which typically takes about 10 minutes. This pre-cooking step ensures the potatoes are perfectly soft when the gratin finishes baking, reducing overall baking time and guaranteeing a creamy texture. Once tender, carefully drain the potatoes.

In the prepared baking dish, gently combine the cooked potatoes with the sliced Paisley Farm Dilled Brussels Sprouts. Sprinkle generously with salt and pepper to season. Next, evenly distribute the shredded Havarti cheese over the potato and Brussels sprout mixture, ensuring every part gets its share of cheesy goodness. Finally, pour the heavy cream uniformly over the entire dish, allowing it to seep into all the layers.

For a final touch of freshness and flavor, sprinkle the minced fresh dill over the top of the gratin, along with any additional salt and pepper to taste.

Bake the gratin for 18-21 minutes, or until the edges are beautifully bubbly, and the top layer of potatoes and cheese begins to turn a tempting golden brown. The timing may vary slightly depending on your oven, so keep an eye on it. Serve this glorious dish piping hot, and watch it disappear!

Any delicious leftovers can be stored in an airtight container in the refrigerator for up to 4 days, or frozen for up to 3 months. Simply reheat gently when ready to enjoy again.

Frequently Asked Questions About Au Gratin Recipes

• Should I pre-cook the potatoes for this recipe? For this particular gratin, we recommend pre-cooking the potatoes to ensure they become perfectly tender and to significantly shorten the overall baking time. It takes only about 10 minutes, and you can easily do it while you’re preparing the Brussels sprouts. If you prefer not to pre-cook, make sure your potato slices are exceptionally thin (around 1/8 inch) and consider covering the dish with foil for the initial part of the baking to allow them to steam and soften properly.
• What types of potatoes work best for gratin recipes? While we used red potatoes for this recipe due to their creamy texture and ability to hold their shape, many varieties work beautifully in gratins. Russet potatoes, known for their starchy texture that creates a wonderfully fluffy interior, or Yukon Golds, with their naturally buttery flavor and smooth consistency, would also yield excellent results. Feel free to use your preferred potato type.
• Can I make this Brussels Sprouts and Potatoes Au Gratin ahead of time? Absolutely! This recipe is ideal for make-ahead preparation, which is a huge time-saver, especially for holidays or dinner parties. You can assemble the entire gratin up to 2 days in advance and store it covered in the refrigerator. Just be sure to allow it to come to room temperature for about 30 minutes before baking to ensure even cooking.
• What baking dish is best for au gratin recipes? For best results, we recommend using a ceramic or enameled cast iron baking dish. These materials conduct and distribute heat very evenly, promoting uniform cooking and a beautifully golden, bubbly crust. We advise against using aluminum dishes, as they can sometimes react with acidic ingredients and may not provide the same even heat distribution.

Expert Tips & Tricks for Perfect Au Gratin

• Proper Brussels Sprout Slicing: To keep your Brussels sprouts intact and ensure they cook evenly and look appealing in the dish, slice them from top to bottom through the core. This technique helps the leaves stay together.
• Achieving Thin Potato Slices: A sharp chef’s knife is essential for getting those perfectly thin potato slices, which are crucial for quick and even cooking in a gratin. For ultimate precision and speed, consider using a mandoline slicer (with caution and a guard!).
• Grate Your Own Cheese: While pre-shredded cheese is convenient, grating your own Havarti makes a significant difference. Freshly grated cheese contains no anti-caking agents, meaning it melts much more smoothly and luxuriously, resulting in a creamier sauce. It’s also often more economical and free from added chemicals.

Delicious Substitutions to Customize Your Gratin

• Lighter Cream Option: If you’re looking to reduce the richness a bit, you can successfully substitute whole milk or even half-and-half for the heavy cream. Keep in mind that the resulting sauce may be slightly thinner but will still be delicious.
• Add a Crunchy Topping: For an extra layer of texture, consider sprinkling the top of your creamy Brussels sprouts and potatoes with panko breadcrumbs, regular breadcrumbs, or a generous layer of grated Parmesan cheese before baking. This will create a delightful, golden-brown crunchy crust.
• Cheese Alternatives: While Havarti is fantastic, this recipe is also incredibly delicious with other melting cheeses. Gruyere cheese, with its nutty and slightly sweet notes, makes for an excellent substitution and adds another dimension of flavor.
• Introduce Savory Bacon: For a more indulgent and smoky twist, try adding some crispy, crumbled bacon to the dish. You can mix it in with the potatoes and Brussels sprouts, or sprinkle it on top before baking.
