I’ll let you in on a little secret: the gooey cheese makes this veggie dish feel like a treat! Pair it with a nice salad for a perfect meal. Who could resist that combo? 😄
Key Ingredients & Substitutions
Zucchini & Yellow Squash: These are the stars of the dish! Both varieties add a mild flavor. You can swap in other veggies like eggplant or bell peppers if you prefer something different.
Cheeses: Cheddar and mozzarella are great for melting and flavor. If you’re looking for a lighter option, try using low-fat cheese or dairy-free alternatives like cashew cream. My personal favorite is adding a bit of smoked gouda for a unique twist!
Cream Cheese: It gives a rich creaminess to the casserole. Neufchâtel cheese is a lighter substitute if you’re counting calories. You can even use Greek yogurt for a healthier take, but add it in smaller amounts as it’s quite tangy.
Herbs and Seasonings: Italian seasoning adds warmth. Feel free to substitute with fresh herbs like basil or thyme if you have them on hand. I love using fresh thyme for a vibrant flavor!
What’s the Best Way to Sauté Vegetables for This Casserole?
Sautéing the vegetables properly is key for building flavor. Here’s how to do it:
- Heat your skillet on medium and add olive oil or butter.
- Add onions and garlic first since they take a bit longer to soften. Cook for 3-4 minutes.
- Then add the zucchini and yellow squash. Stir occasionally and cook for about 5-7 minutes until they just start to soften. Don’t overdo it; they will cook more in the oven.
- Remember to let them cool slightly before mixing them with the cheese — this helps maintain a good texture in the casserole!
