Pat dry your canned or frozen artichoke hearts with paper towels before chopping to remove excess moisture, preventing a watery dip and ensuring optimal cheese adhesion.

Mix all ingredients in a bowl and let sit for 5 minutes before transferring to the baking dish—this allows flavors to meld and helps the cheese distribute evenly throughout.

Use equal parts mayo and sour cream as your base, then add just enough to bind—too much liquid creates a soup, while the right amount keeps the dip creamy and spreadable.

Shred your own cheddar and parmesan from blocks rather than using pre-shredded varieties, which contain anti-caking agents that prevent smooth melting and create a grainy texture.

Seed your diced chilis before adding to control heat level—remove seeds for mild flavor or keep them for authentic spice that won't overpower the creamy cheese base.
