Ingredients You’ll Need
The beauty of this recipe is in its simplicity, yet every ingredient plays a crucial role in building layers of flavor and texture. From the humble potato to the golden brown butter and the sweet onions, each component works together beautifully to create a dish that’s both elegant and satisfying.
- 4 medium potatoes: Choose firm, starchy potatoes for the best slice-and-crisp effect.
- 4 tablespoons butter: Essential for that rich, nutty brown butter flavor that coats the potatoes.
- 2 onions, thinly sliced: These develop a sweet complexity when caramelized slowly.
- 2 tablespoons olive oil: Helps gently cook the onions without burning, preserving their sweetness.
- 1/2 teaspoon salt: Enhances all the flavors and helps with seasoning.
- 1/4 teaspoon black pepper: Adds a subtle kick that balances the richness.
How to Make Brown Butter Hasselback Potatoes with Caramelized Onions Recipe
Step 1: Prepare and Slice the Potatoes
Start by preheating your oven to 200°C (400°F). Carefully slice the potatoes into thin wedges, cutting almost all the way through but stopping just before you reach the bottom. A useful trick is to place chopsticks alongside the potatoes while slicing; this prevents cutting all the way through and keeps the potato intact during baking. This technique is what gives hasselback potatoes their signature fan-like shape and ensures every bite has crisp edges and tender interiors.
Step 2: Make the Brown Butter
Place the butter in a pan over medium heat and let it melt slowly. Keep a close eye as it begins to foam and turn golden brown. Once it has a nutty aroma and golden color, immediately remove it from the heat to avoid burning. This brown butter is the star of this recipe, infusing the potatoes with deep, toasty richness that you won’t get from plain melted butter.
Step 3: Season and Roast the Potatoes
Brush the melty brown butter generously over the sliced potatoes, making sure it seeps into each cut. Sprinkle salt and black pepper evenly over the top to season. Place the potatoes on a baking sheet and slide them into the oven. Bake for 40 to 50 minutes, basting the potatoes with more brown butter halfway through to build layers of crispness and flavor. You’ll know they are done when the outsides are beautifully crisp and the insides soft and tender.
Step 4: Caramelize the Onions
While the potatoes roast, heat the olive oil in a skillet over medium-low heat. Add the thinly sliced onions and cook slowly, stirring occasionally, until they turn a rich golden brown. The key here is patience—rushing the onions won’t bring out their full sweetness. This step transforms their sharpness into a luscious, sweet counterpoint to the savory potatoes.
Step 5: Assemble and Serve
Once the potatoes are done, gently transfer them to a serving dish and pile the caramelized onions on top. The contrast of the rich brown butter potatoes and sweet onions creates a truly memorable dish that’s visually stunning and incredibly tasty.
How to Serve Brown Butter Hasselback Potatoes with Caramelized Onions Recipe
Garnishes
To add a fresh, vibrant touch, scatter some chopped fresh herbs like thyme, rosemary, or parsley over the top just before serving. A sprinkle of flaky sea salt also elevates the flavors and adds a delightful crunch. If you want to indulge further, a light dusting of grated Parmesan or crumbled blue cheese can create a wonderful flavor contrast.
Side Dishes
This recipe pairs exceptionally well with roasted meats, grilled vegetables, or even a simple green salad. Its robust, buttery flavors complement almost any main course, making it an incredibly versatile side that shines on the dinner table.
Creative Ways to Present
For an impressive showstopper, try serving individual potatoes on small plates, each topped with caramelized onions and a delicate herb garnish. Alternatively, place the whole hasselback potatoes on a rustic wooden board with bowls of different sauces or flavored butters for guests to customize their bites. It’s an inviting way to turn this humble dish into a centerpiece.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, place them in an airtight container and store them in the refrigerator for up to three days. The potatoes may lose some crispiness but will still deliver that lovely brown butter and onion flavor when reheated.
Freezing
While you can freeze portions of the hasselback potatoes, it’s best to freeze them before baking. Wrap the sliced, butter-brushed potatoes tightly and freeze in a sealed bag for up to one month. When ready to use, thaw in the refrigerator and bake as usual.
Reheating
Reheat leftovers in a preheated oven at 180°C (350°F) for about 10-15 minutes to restore crispiness and warm through. Avoid microwaving as it tends to make the potatoes soggy and less appealing.
FAQs
Can I use sweet potatoes instead of regular potatoes?
Absolutely! Sweet potatoes will add a unique sweetness and vibrant color. Just keep an eye on the baking time, as they can cook a little faster than regular potatoes.
How do I ensure my brown butter doesn’t burn?
The key is to watch it carefully and stir often. Once the butter foams and turns a golden brown with a nutty aroma, remove it from the heat immediately to prevent burning.
Can I make this dish vegan?
Yes, you can substitute butter with a plant-based vegan butter and use olive oil for basting the potatoes. The caramelized onions cooked in olive oil fit perfectly into a vegan diet.
What type of potatoes work best?
Firm, starchy potatoes like Yukon Gold or Russet are ideal because they hold their shape and crisp up nicely without becoming mushy.
How thin should I slice the potatoes?
Thin slices around 3-5 mm are perfect; they allow the butter to penetrate each layer while keeping the potato intact for that beautiful hasselback effect.
