Honestly, this recipe snuck into my meal rotation during one of those “I-have-nothing-planned-and-not-much-in-the-fridge” moments. I had some yellow squash languishing in the crisper drawer and a nearly empty box of Ritz crackers that begged for attention.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most are pantry staples or easy to find in any grocery store, and there’s room for substitutions if needed.

• Yellow squash: About 4 cups, sliced thin (fresh summer squash is best; if out of season, frozen works in a pinch)
• Onion: 1 medium, finely chopped (adds sweetness and depth)
• Garlic: 2 cloves, minced (fresh is best for that punch of flavor)
• Butter: 4 tablespoons, divided (unsalted preferred, but salted works too)
• Cream cheese: 4 ounces, softened (I like Philadelphia for creamy texture)
• Sharp cheddar cheese: 1 ½ cups, shredded (look for a good-quality aged cheddar for punchy flavor)
• Mayonnaise: ½ cup (this helps keep the casserole moist and rich)
• Ritz crackers: 1 ½ cups, crushed (the star of the crunchy topping; no substitutions if you want that iconic flavor)
• Milk: ¼ cup (whole milk gives the best creaminess, but 2% works)
• Salt and pepper: To taste (season carefully to balance the flavors)
• Optional: A pinch of cayenne or smoked paprika for subtle warmth

If you’re looking to make this casserole gluten-free, almond flour or gluten-free crackers can replace Ritz, though the texture will be a bit different. For a dairy-free version, swap cream cheese and cheddar with plant-based alternatives and use vegan butter.

Equipment Needed

• Baking dish: A 9×13-inch casserole dish is ideal for even baking and that perfect crispy top.
• Mixing bowls: At least two, one for the squash mixture and one for the cracker topping.
• Skillet: For sautéing onions and garlic to bring out their sweetness.
• Cheese grater: Freshly shredded cheddar melts better and tastes way fresher.
• Measuring cups and spoons: Precision helps balance flavors, especially with seasoning.
• Food processor or rolling pin: For crushing Ritz crackers evenly (a food processor makes it quick, but a rolling pin with a zip-top bag works perfectly fine).

I’ve tried this recipe with different casserole dishes—glass, ceramic, you name it—and honestly, they all work fine. Just watch the baking time if you switch sizes. I usually keep a small cast-iron skillet handy for sautéing; it heats evenly and is easy to clean.

Preparation Method

1. Preheat your oven to 350°F (175°C). This gives the oven time to reach the perfect temperature while you prep.
2. Prepare the squash: Slice about 4 cups of yellow squash thinly. If you want to reduce moisture, sprinkle a pinch of salt on the slices and let them sit in a colander for 10-15 minutes, then gently squeeze out excess water. This step helps keep the casserole from getting watery.
3. Sauté the aromatics: In a medium skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Toss in the garlic and cook another minute until fragrant. Remove from heat and set aside.
4. Mix the creamy base: In a large bowl, blend the softened cream cheese, mayonnaise, and milk until smooth. Stir in the sautéed onion and garlic mixture and season with salt, pepper, and a pinch of cayenne or smoked paprika if using.
5. Combine squash and cheese: Fold the sliced squash into the creamy mixture, then stir in 1 cup of shredded sharp cheddar cheese. Make sure everything is coated well.
6. Assemble the casserole: Pour the squash mixture into your greased 9×13-inch baking dish, spreading it evenly.
7. Prepare the Ritz topping: In a small bowl, crush 1 ½ cups of Ritz crackers until fine crumbs form. Melt the remaining 2 tablespoons of butter and mix it with the crumbs until well combined and crumbly.
8. Top the casserole: Evenly sprinkle the buttery Ritz crumbs over the squash mixture.
9. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, until the top is golden brown and the filling is bubbling around the edges.
10. Rest before serving: Let the casserole sit for 5-10 minutes to set slightly. This makes serving easier and the flavors meld together nicely.

One thing I learned the hard way: don’t skip the resting time. It’s tempting to dig right in, but the casserole firms up beautifully and tastes even better after resting.

Also, keep an eye on the top in the last 10 minutes of baking—if it’s browning too fast, tent loosely with foil to avoid burning.

Cooking Tips & Techniques

One of the keys to a great squash casserole is managing moisture. Squash can be watery, and if you don’t handle it right, your casserole turns out soggy instead of creamy and rich. Salting the squash before mixing helps pull out excess water. Just don’t skip the gentle squeeze afterward.

Using fresh sharp cheddar cheese makes all the difference. Pre-shredded cheese often has anti-caking agents that can affect melting, so grating your own really pays off. It melts smoother and blends better with the cream cheese base.

For the Ritz cracker topping, the butter-to-cracker ratio is crucial. Too little butter, and the topping won’t crisp nicely; too much, and it gets greasy. I stick to 2 tablespoons of butter for 1 ½ cups of crumbs—it’s just right for that classic buttery crunch.

Pro tip: If you want extra flavor, toast the crushed Ritz crumbs in a dry skillet for a minute before mixing with butter. It adds a slight nuttiness that’s delicious.

Timing-wise, this recipe is forgiving. You can prep the squash mixture ahead and refrigerate it for a few hours before baking. Just add the Ritz topping right before popping it in the oven.

Variations & Adaptations

• Vegetarian Option: This recipe is naturally vegetarian, but for a vegan twist, swap cream cheese and cheddar for plant-based versions and use vegan butter. Add nutritional yeast for a cheesy flavor.
• Spicy Kick: Stir in diced jalapeños or a dash of hot sauce into the creamy base for a little heat that contrasts nicely with the buttery topping.
• Seasonal Twist: In fall, mix in some cooked, crumbled bacon or diced ham for added savory depth. Or swap half the squash with zucchini for a blend of textures.
• Low-Carb Adaptation: Use almond flour mixed with crushed pork rinds instead of Ritz crackers for the topping to keep it keto-friendly.
• My Favorite Variation: Once, I added a handful of fresh thyme and a little grated Parmesan to the topping. It gave the casserole a subtle herbal note that was surprisingly good.

Serving & Storage Suggestions

This Cozy Southern Loaded Squash Casserole is best served warm, fresh out of the oven with that crunchy Ritz topping still intact. It pairs beautifully with roasted chicken, glazed ham, or even a simple green salad to balance the richness.

Leftovers reheat well in the microwave or oven. To keep the topping crispy, I recommend reheating in a 350°F (175°C) oven for 10-15 minutes rather than the microwave. Flavors tend to deepen after sitting overnight, making it even tastier the next day.

Store leftovers in an airtight container in the refrigerator for up to 3 days. You can also freeze the casserole before baking—just cover tightly and freeze for up to 2 months. Thaw overnight in the fridge and bake as directed, adding a few extra minutes if needed.

Nutritional Information & Benefits

Each serving of this casserole offers a comforting dose of vegetables from the yellow squash, which is low in calories but rich in vitamins A and C and fiber. The cheddar and cream cheese provide calcium and protein, though this dish is definitely on the indulgent side.

For those watching carbs, the Ritz cracker topping adds some simple carbs, but portion control helps keep it balanced. You can easily adjust fat content by swapping full-fat dairy for lighter versions, though the richness is part of the charm.

Overall, this casserole is a satisfying way to include squash in your diet without sacrificing flavor or texture, making it a crowd-pleasing vegetable side with a Southern soul.
