Asiago, Potato, and Bacon Gratin: A Symphony of Flavors

The first time I tasted a potato gratin, I was a wide-eyed culinary student interning at a small bistro in the French countryside. The aroma alone, a blend of earthy potatoes, rich cream, and nutty cheese, transported me. But the dish itself? Pure comfort. It was a revelation of how simple ingredients, treated with care, could create something truly extraordinary. This Asiago, Potato, and Bacon Gratin brings a slightly different, more rustic elegance to that classic, swapping out the heavy cream for milk and adding the savory punch of bacon and the sharp tang of Asiago. It’s a dish that evokes warmth, laughter, and shared moments around the table.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 35 minutes
• Total Time: 55 minutes
• Servings: 6
• Yield: 1 gratin
• Dietary Type: Not Gluten-Free

Ingredients

• 1 1⁄2 lbs peeled Yukon gold potatoes, cut into 1/4-inch thick slices
• 1 teaspoon salt, divided
• 2 tablespoons minced shallots
• 1⁄4 cup all-purpose flour
• 2 cups 1% low-fat milk, divided
• 3⁄4 cup grated Asiago cheese
• 1⁄4 cup chopped fresh chives
• 1⁄4 teaspoon fresh ground pepper
• 4 slices bacon, cooked and crumbled
• 1⁄4 cup grated fresh Parmesan cheese

Equipment Needed

• Large saucepan
• 8-inch square baking dish
• Non-stick cooking spray
• Whisk
• Medium saucepan

Instructions

1. Begin by preparing the potatoes. Place the sliced Yukon gold potatoes in a large saucepan and cover them with water. Bring the water to a boil over high heat.
2. Once boiling, reduce the heat to simmer and cook the potatoes for about 5 minutes, or until they are almost tender. They should still have a slight bite to them. Drain the potatoes thoroughly.
3. Sprinkle the drained potatoes evenly with 1/4 teaspoon of the salt. Set them aside and keep warm.
4. Next, prepare the cheese sauce. Heat a medium saucepan coated with non-stick cooking spray over medium heat. Add the minced shallots and sauté for approximately 2 minutes, or until they are tender and translucent.
5. Sprinkle the all-purpose flour over the sautéed shallots. Stir continuously to incorporate the flour, creating a roux. This will help thicken the sauce.
6. Gradually add 1/2 cup of the 1% low-fat milk to the saucepan. Use a whisk to stir continuously, ensuring the flour mixture blends smoothly with the milk and no lumps form.
7. Gradually add the remaining 1 1/2 cups of 1% low-fat milk to the saucepan, continuing to whisk until the sauce is well blended and smooth.
8. Cook the sauce over medium heat for about 9 minutes, stirring frequently with the whisk. The sauce should thicken as it cooks. Avoid letting the sauce scorch on the bottom of the pan by stirring consistently.
9. Remove the saucepan from the heat. Add the remaining 3/4 teaspoon of salt, the grated Asiago cheese, chopped fresh chives, fresh ground pepper, and crumbled bacon to the sauce. Stir well to combine all the ingredients and ensure the cheese is melted and evenly distributed throughout the sauce.
10. Preheat your oven to 350°F (175°C).
11. Coat an 8-inch square baking dish with non-stick cooking spray. This will prevent the gratin from sticking to the dish.
12. Arrange half of the warm potato slices in a single layer at the bottom of the prepared baking dish.
13. Pour half of the prepared cheese sauce evenly over the layer of potatoes.
14. Top with the remaining potato slices, arranging them in an even layer.
15. Pour the remaining cheese sauce over the second layer of potatoes, ensuring they are well coated.
16. Sprinkle the grated fresh Parmesan cheese evenly over the top of the gratin.
17. Bake in the preheated 350°F (175°C) oven for approximately 35 minutes, or until the cheese is bubbly and lightly browned.
18. Remove the gratin from the oven and let it cool slightly before serving.

Expert Tips & Tricks

• For a smoother sauce, ensure the roux (flour and shallot mixture) is thoroughly cooked before adding the milk.
• If you prefer a richer flavor, you can use whole milk instead of 1% low-fat milk, but this will increase the fat content.
• To prevent the potatoes from sticking to the bottom of the pan while boiling, add a tablespoon of olive oil to the water.
• If the top of the gratin is browning too quickly in the oven, cover it loosely with foil for the last 10-15 minutes of baking.
• For a deeper bacon flavor, use thick-cut bacon and render the fat before crumbling it into the sauce. Save the bacon fat to roast vegetables.
• Make-ahead tip: Assemble the gratin a day in advance, cover, and refrigerate. Add about 10-15 minutes to the baking time if baking from cold.

Serving & Storage Suggestions

This Asiago, Potato, and Bacon Gratin is delicious served warm, straight from the oven. It pairs beautifully with roasted chicken, grilled steak, or even a simple green salad. Garnish with extra fresh chives for a pop of color.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in short intervals. The texture may change slightly upon reheating, but the flavor will remain delicious. Freezing is not recommended as the texture of the potatoes and sauce may become watery.

FAQs (Frequently Asked Questions)

Q: What can I substitute for the Asiago cheese?

A: Parmesan cheese is a good substitute, offering a similar salty and nutty flavor. Pecorino Romano would also work well.

Q: How do I prevent the potatoes from browning before they are fully cooked?

A: If the top is browning too quickly, cover the gratin loosely with aluminum foil during the last 10-15 minutes of baking.
