📖 Variations
- Add these french fried onions to the top before baking.

- Add some leftover shredded chicken breast or chopped, cooked ham to the squash mixture for a great main dish idea.

- The cornbread stuffing mix adds a hearty sweetness to the dish, but you could use an herb stuffing mix, instead.
- If you don't want so much stuffing use 1 box and ¼ cup of butter and skip the first layer of stuffing.
- Before serving, garnish with summery, fresh herbs, like chives or parsley.

🥫 Storage
Squash casserole with stuffing keeps pretty well. Wrap up any leftovers in an airtight container, or cover the top of the casserole dish with plastic. Refrigerate for up to three days.
You can microwave individual portions until heated to your liking. Alternatively, rewarm the casserole in the oven, tented loosely with foil.
To enjoy yellow summer squash all year long, you can freeze leftovers in a freezer-safe container. It'll last for about three months.
Thaw in the refrigerator before microwaving or warming in the oven.
You can also make ahead and freeze the casserole before baking. Just leave the stuffing off until you're ready to bake.
💭 Things to know
Expert Tip: Don't overcook your squash and onions. Since they'll continue baking a bit in the oven, just get them tender enough to prick with a fork.
- There's no need to peel summer squash as long as it's not so big that it develops tough outer skin. If it's that big you don't want to use it anyhow.
- Try to use smaller, tender squash in this easy squash casserole. They're a bit sweeter and slightly more flavorful than larger ones.
- Slice your squash as evenly as you can. Similar-sized pieces will cook more evenly, ensuring every bite of your finished casserole is perfect!
- Use a large saucepan, preferably one that is a little flatter than higher, to cook the squash and onions. This will help them all cook at the same rate.
- After steaming the veggies, be sure to pat them dry very well. Use multiple towels if necessary to prevent your final casserole from tasting watery.
- Always grate your cheese from a block! The pre-grated cheese has stuff on it to keep it from clumping which ALSO hinders the melting!
👩🍳 FAQs
You sure can! After spooning the squash mixture into the casserole dish and covering it with the remaining stuffing mixture, seal with plastic wrap or foil.
Refrigerate for up to four days, or freeze for three months. Let thaw in the fridge before baking.
This is my favorite recipe to make in the fall with my final fresh squash. Then, I save a batch (or two) in the freezer for Thanksgiving or Christmas dinner. Check "side dish" off your busy holiday to-do list!
Use any dry stuffing mix you can find in the grocery store. I like the Stove Top or Pepperidge Farm brands. If you're feeling ambitious, use homemade stuffing—extra bragging points if you do!
No, I wouldn't recommend it! Butternut squash is in the winter squash category, along with acorn and other heartier varieties. It takes a lot longer to cook than yellow.
On the other hand, yellow squash and zucchini are considered summer squash, and they're softer, with higher water content. They don't take as long to cook, taste great against gooey cheese, and perfectly complement the buttery stuffing on top!
