Ingredients You’ll Need

Here’s what you’ll want to gather before you start:

• Yellow squash (fresh is best, but frozen works)
• Green chiles (Hatch or Anaheim for mild, jalapeño for more heat)
• Onion, finely chopped
• Eggs (helps bind the casserole)
• Shredded cheese (cheddar, Monterey Jack, or a blend)
• Sour cream or mayonnaise for creaminess
• Bread crumbs or crushed crackers for the topping
• Salt, pepper, and optional spices like cumin or garlic powder

Optional Add-ins:

• Corn (adds sweetness and texture)
• Jalapeños (for extra spice)
• Diced tomatoes
• Cooked bacon or sausage

Choosing the Best Squash and Chiles

• Yellow squash is the top pick for its soft texture and mild flavor.
• Zucchini can be substituted, but may have more moisture.
• Fresh squash provides better texture than frozen, which can be watery.
• Drain cooked squash thoroughly or squeeze excess water out using a cheesecloth.

For the chiles:

• Hatch chiles bring an authentic Southwestern flavor.
• Anaheim chiles are milder and widely available.
• Canned diced green chiles are a great shortcut.
