Preparation

Step 1

Preheat oven to 350°F.

In a Dutch oven, melt the butter over medium heat. Add onion, mustard, salt and pepper; cook until onion is tender 6 to 8 minutes. Add garlic; cook until fragrant, about 30 seconds. Whisk in flour; continue whisking 3 to 5 minutes.

Whisk in milk; bring to a boil. Reduce heat; simmer, uncovered, until sauce is thickened slightly, 8 to 10 minutes. Slowly stir in 2 cups cheddar cheese; stir in Monterey Jack cheese. Add potatoes and toss to coat. Simmer 10 minutes, stirring frequently to avoid scorching.

Transfer potato mixture to a greased 13 x 9 inch baking dish. Top with remaining cheddar cheese. Bake, uncovered, for 1 hour. Top with bread crumbs; return to oven until the potatoes are tender, 10 to 15 minutes. Let stand 15 minutes before serving. If desired sprinkle with minced chives.

Shred the cheese off the block for a creamier texture and bolder flavor. for a smoother sauce use full-fat milk and cheese. Low and slow is key, too much heat will cause the sauce to break. As soon as the sauce comes to a boil, turn down the heat.
