Cheesy Artichoke Dip Recipe

"With Parmesan and Swiss cheese and loads of artichoke, this easy and classic dip is big enough to feed a crowd at your next big game day party. What to buy: Be sure to use good-quality cheese for this recipe. Avoid buying the pre-grated kind; it won’t offer much flavor. If you don’t like Gruyère, an aged cheddar is a good substitute. Panko is coarse Japanese-style breadcrumbs, available in many grocery stores. Game plan: There are versions of this dip that don’t require the flour, but they start to separate as they get cold. This dip holds together long after it cools down, making it ideal for a party setting. The dip can be made through step 3 up to 1 day ahead. Cool it to room temperature, cover, and store in the refrigerator. When you’re ready to finish the dip, let it sit at room temperature for at least 15 minutes before baking.
