Tips
Sauté vegetables until onions are translucent and soft to develop sweet, caramelized flavors that balance the rich cheese and mayo base.
Keep mayo and cheese ratio constant when adjusting vegetables; substitute with seeded tomatoes, zucchini, artichokes, or hot peppers for variety.
Use an 8x8 glass or ceramic baking dish for even heating and easy serving directly to guests.
Good to Know
Cover and refrigerate up to 3 days. Reheat in 350F oven for 10-15 minutes until warm.
Prepare mixture without baking up to 24 hours ahead; cover and refrigerate. Bake before serving.
Warm from oven with corn chips, tortilla chips, or crackers. Transfer to serving bowl or keep in baking dish.
Common Mistakes
Don't skip sautéing vegetables to avoid a watery, raw-tasting dip.
Don't overbake to avoid cheese breaking or developing brown edges; watch closely after 15 minutes.

FAQ
Can I make this dip ahead of time?
Yes, assemble the dip up to 24 hours in advance, cover, and refrigerate. Bake just before serving for best texture and melted cheese.
What if I don't have both mozzarella and cheddar?
Use 4 cups of either cheese alone, or substitute with Monterey Jack, Gruyere, or a blend. Maintain the 4-cup total for proper consistency.
Can I freeze this dip?
Freeze unbaked dip in an airtight container up to 2 months. Thaw overnight in fridge, then bake as directed. Cooked dip does not freeze well due to mayo separation.
