Ingredients for Southern Squash Casserole
Now let’s gather the simple ingredients that make this Southern squash casserole sing. Measure carefully – good cooking is part science, part love!
- 2 lbs yellow squash: sliced ¼-inch thick (about 4 medium squash)
- ½ cup onion: finely chopped (yellow or sweet onion works best)
- ½ cup butter: divided – ¼ cup melted for filling, ¼ cup melted for topping
- 1 cup sharp cheddar: freshly shredded (none of that pre-shredded stuff!)
- ½ cup sour cream: full-fat for best texture
- 1 tsp salt: I use kosher salt – adjust to taste
- ½ tsp black pepper: freshly ground if you can
- 1 sleeve buttery crackers: Ritz or similar (about 35 crackers)
Ingredient Notes & Substitutions
Ran out of something? No worries – here’s how to pivot:
- Sour cream swap: Greek yogurt works in a pinch, but add a teaspoon of lemon juice for tang
- Gluten-free? Use gluten-free crackers or crushed pork rinds for the topping
- Frozen squash: Thaw completely and squeeze out excess liquid before using
- Want more oomph? Toss in crumbled bacon or diced jalapeños for a kick
How to Make Southern Squash Casserole
Alright y’all, let’s get this Southern squash casserole show on the road! Follow these steps and you’ll have a dish that’ll make your grandma proud.
- Preheat that oven: Crank it to 350°F right away – no cheating with a cold oven!
- Cook your squash: Toss those sliced squash and chopped onions in a pot of boiling water. Let ’em swim for about 10 minutes until fork-tender. Drain ’em well – I mean REALLY well – or you’ll end up with a soggy mess.
- Mash and mix: Use a potato masher or fork to gently smash the squash (leave some texture!). Stir in ¼ cup melted butter, cheese, sour cream, salt, and pepper until it’s all cozy together.
- Layer it up: Spread that creamy squash mixture into a greased 2-quart baking dish. I like using my trusty Pyrex – it bakes evenly every time.
- Top it right: Crush those buttery crackers (put ’em in a bag and whack ’em with a rolling pin – great stress relief!). Sprinkle over the casserole, then drizzle with the remaining melted butter. Oh that golden crust is gonna be incredible!
- Bake to perfection: Pop it in the oven for 25 minutes until the edges are bubbly and the topping is golden brown. Your whole house will smell like a Southern kitchen!
Pro Tips for the Best Southern Squash Casserole
Listen close now – these little tricks make all the difference:
- Drain like your life depends on it: Press that cooked squash in a colander with paper towels to banish excess water.
- Toast those crackers: Spread ’em on a baking sheet at 300°F for 5 minutes before crushing for extra crunch.
- Taste before baking: Adjust salt and pepper after mixing – squash sweetness varies by season.
Serving Suggestions for Southern Squash Casserole
Oh, sweet mercy—this Southern squash casserole wasn’t meant to fly solo! It’s the ultimate team player on your dinner table. Pair it with crispy fried chicken (extra points if it’s your mama’s recipe) or pile it next to smoky grilled pork chops for that classic meat-and-three vibe. Come Thanksgiving, it holds its own against turkey and dressing like they grew up together. Want to fancy it up? Scatter fresh parsley or chives over top right before serving—those green flecks make it look mighty pretty next to all that golden-brown goodness. Just don’t be surprised when your guests start calling it the “best side dish in the South” before they’ve even touched their cornbread!
Storing and Reheating Southern Squash Casserole
Now listen here – I know you’ll probably gobble this Southern squash casserole right up, but if you’ve got leftovers (miracle of miracles!), here’s how to keep ’em tasting fresh:
- Fridge savvy: Store cooled casserole covered tight for 3-4 days – any longer and that topping gets sad.
- Freezer trick: Portion it unbaked (topping and all) in foil pans – it freezes beautifully for 2 months. Just add 10 extra minutes when baking from frozen.
- Reheating magic: Always use the oven at 350°F for 15-20 minutes to keep that cracker crunch. The microwave? Bless your heart, that’s a one-way ticket to Soggyville!
Southern Squash Casserole Variations
Don’t get me wrong—I love the classic version, but sometimes my Southern squash casserole needs a little personality makeover! Here are my favorite twists that still stay true to its soul-warming roots:
- Southwestern flair: Mix in a cup of sweet corn and diced jalapeños for a kick – top with pepper jack cheese!
- Italian cousin: Swap cheddar for Parmesan and add a pinch of garlic powder – basil garnish makes it fancy.
- Crunch upgrade: Mix crushed crackers with panko breadcrumbs and toasted pecans for next-level texture.
- Sunday special: Fold in crumbled bacon and use the drippings instead of butter (trust me on this one).
Really, once you’ve got the basic recipe down, your squash casserole imagination can run wild – just like my aunt Martha’s does at every family reunion!
Southern Squash Casserole Nutritional Information
Now, let’s be honest here—this ain’t diet food, y’all! But good Southern cooking feeds the soul, not just the body. For a standard serving (about 1 cup), expect roughly 280 calories with 18g fat (that’s the good butter and cheese talking!), 8g protein, and 3g fiber from those beautiful squash. Remember—nutrition changes faster than a summer rainstorm based on your specific ingredients and portion sizes. So eat up and enjoy every cheesy, buttery bite!
Southern Squash Casserole FAQs
Y’all got questions? I’ve got answers! Here are the things folks ask me most about making the perfect Southern squash casserole:
- Can I use zucchini instead of yellow squash? Bless your heart, of course you can! Zucchini works great—just peel it first so the skins don’t turn weird colors when baked. You might need to drain it extra well though—zucchini holds more water.
- Help! My topping isn’t crispy enough! Two tricks: First, toast those crackers before crushing (just 5 minutes at 300°F). Second, make sure you’re using enough butter—that golden drizzle is what makes the magic happen!
- Can I make this ahead? Absolutely! Assemble everything (without baking) and refrigerate overnight. Just add 5 extra minutes to the baking time. The flavors actually get better!
- What if I don’t have Ritz crackers? Any buttery cracker works—Saltines, Club crackers, even crushed Cheez-Its for an extra cheesy kick (my nephew’s favorite).
- Can I freeze leftovers? You bet! Freeze in individual portions and reheat in the oven at 350°F—the microwave will murder that beautiful crispy topping.
Still got questions? Drop ’em in the comments—I’ve been making this Southern squash casserole since I could reach the stove, so no question’s too silly!
