Naturally, I put my own twist on this dish by spicing it up with the help of green chiles and crispy onions, which are one of my favorite foods. This one of the best yellow squash casserole recipes to be on rotation for your summer squash recipes from the garden!

🌶️Ingredients You’ll Need

  • Yellow Squash – Yellow squash provides a mild and slightly sweet flavor to the recipe, as well as a tender texture when cooked.
  • White Onion & Minced Garlic – The onion adds a savory and slightly sweet flavor, while minced garlic contributes a pungent and aromatic taste.
  • Butter Crackers (Ritz) – Act as a crispy and buttery topping, adding a delightful texture and flavor to the recipe.
  • Diced Green Chiles – Provides a mild to medium level of heat and a tangy flavor, adding a hint of spiciness and complexity to the dish.
  • Sharp Cheddar Cheese (shredded) – Brings a rich and tangy flavor, and when shredded, it melts beautifully, giving the dish a creamy and cheesy element.
  • Eggs – Serve as a binding agent, helping to hold the ingredients together and providing structure to the recipe.
  • Heavy Cream – Adds richness and creaminess to the dish, creating a smooth and velvety texture and enhancing the overall flavor.
  • Unsalted Butter – Contributes a rich and creamy buttery taste, as well as providing moisture to the dish and enhancing the flavors of the other ingredients.
  • Crispy Onions (French’s) – Crispy onions act as a crunchy topping, adding texture and a savory, slightly sweet flavor to the recipe.
  • Kosher Salt – Used to season the dish, enhancing the flavors of all the ingredients and bringing balance to the overall taste.
  • Black Pepper – Adds a hint of spiciness and warmth to the dish, enhancing the flavors and providing a subtle kick.
  • Cooking Oil – Used to sauté or fry ingredients, preventing them from sticking to the pan and adding moisture and flavor to the dish. We like using a healthy cooking oil such as olive oil or avocado oil.

📖How To Make Green Chile Yellow Squash Casserole

1️⃣ Prepare for baking: Preheat oven to 400F. Get out a baking dish or casserole dish and set aside.

2️⃣Saute vegetables: In a large skillet or pot, heat up avocado oil over medium-high heat. Add in diced squash, onion, garlic, salt, and pepper. Saute for 8-10 minutes or until vegetables are cooked through and tender. Drain excess liquid from the vegetable mixture.

3️⃣ Assemble the crunchy topping: In a large bowl, mix together the cracker crumbs, cheddar cheese, and crispy onions until evenly distributed. Remove half of the mixture into a smaller bowl to use for the topping.

4️⃣ Layer the squash casserole: Add cooked and drained squash to the large bowl and stir in melted butter, beaten eggs, and heavy cream to make the sauce. Mix gently until all ingredients are combined.

5️⃣ Bake and cool: Add the squash mixture to a large greased casserole dish or baking dish that is (9×13) and spread in an even layer. Sprinkle with the remaining cracker, cheese, and onion mix. Bake at 400 for 40 minutes. Remove from oven and let sit 10 minutes before serving. Serve hot.

🧀Variations & Substitutions

  • Velveeta Yellow Squash Casserole: Instead of shredded cheddar cheese, you can use shredded Velveeta as a replacement. This will add a more creamy texture.
  • Use green zucchini: Instead of using just yellow squash, you can also use a mix of yellow and green squash or just zucchini for a green and yellow squash casserole.
  • Butter crackers: We recommend using Ritz crackers or butter crackers for the topping, but you can also use a mix of saltine crackers or panko breadcrumbs.
  • Creamy sauce: To incorporate sour cream or mayo into a recipe for yellow squash casserole, simply mix it in with the other ingredients before baking. Sour cream or mayonnaise will add a creamy and tangy element to the casserole, enhancing its texture and flavor.
  • Add some herbs: Increase the garden fresh taste by adding herbs such as fresh thyme, rosemary, or basil to the mixture before baking.
  • Switch up the cheese: Instead of sharp cheddar cheese, feel free to use parmesan cheese, mozzarella, or gouda.
  • Change the shape: Instead of dicing the squash, you can achieve a different texture by slicing the yellow squash. Just make sure every slice is relatively the same size to ensure even cooking.
  • Gluten free: To make a gluten free green chili squash casserole, you’ll need to find gluten free butter crackers and gluten free fried onions to make the topping. Be sure to check all other ingredients for wheat.

❄️Storing & Freezing

Storing: Leftovers of yellow squash casserole can be stored in an airtight container in the refrigerator for up to 3-4 days.

Freezing: If you want to freeze the casserole, let it cool completely, then transfer it to a freezer-safe container or wrap it tightly with aluminum foil. Label the container with the date and freeze for up to 3 months. Make sure it thaws overnight in the fridge before reheating.

Reheating: To reheat the casserole, preheat your oven to 350°F (175°C). Place the thawed or refrigerated casserole in the oven and bake for about 20-25 minutes or until heated through. Alternatively, you can reheat individual servings in the microwave for a few minutes until warmed.

  1. You also don’t mention when the first half of the cracker cheese and crispy onion mixture is added.
