Ingredients

Scale

What You Need:

    • 2 lbs zucchini (I buy the smaller ones, they’re less watery)

    • 1 cup Colby-Jack cheese, shredded (save â…“ cup for top)

    • â…“ cup cottage cheese (I use the small curd kind)

    • â…“ cup mayo (real mayo, not the light stuff)

    • 1 egg

    • 1 tsp garlic powder

    • 1 tsp onion powder

    • Salt for seasoning plus extra for draining

    • Black pepper if you want it


Instructions

Step 1: Get That Water Out (Seriously, Don’t Skip This!) Slice your zucchini about ¼-inch thick – I eyeball it, doesn’t have to be perfect. Toss all the slices with a good amount of salt in a colander and let them sit for 30 minutes. I usually start this first, then prep everything else. Blot them with paper towels or clean kitchen towels after 30 minutes.

Step 2: Oven and Pan Prep Preheat your oven to 350 degrees and spray a 9×9 baking dish with non-stick cooking spray. I’ve attempted to skip the spray in the past — don’t do this unless you want to be scrubbing melted cheese off the dish.

Step 3: Mix the Good Stuff In a large bowl, combine cottage cheese, mayo, egg, garlic powder, onion powder, salt and pepper. Whiz it up until smooth – it will form a thick creamy sauce.

Step 4: Add Most of the Cheese Fold in â…” of your shredded cheese, saving the rest for the top. This is where it starts looking really good!

Step 5: Combine Everything Add your dried zucchini to the cheese mixture and fold gently until every piece is coated. Don’t be rough with it – zucchini can get mushy if you overmix.

Step 6: Bake Time Spread everything in your prepared dish and top with the remaining cheese. Bake for 35-40 minutes until the top is golden and it’s bubbling around the edges.

Step 7: Let It Rest This is the hardest part – let it cool for 10 minutes before you dig in. It needs time to set up, trust me on this one!

Notes

This recipe is pretty forgiving. If you mess up the measurements a little, it’ll still taste good. The cottage cheese was my mom’s idea – she said it would make it creamier without adding carbs. She was right, as usual.
