This low-carb Zucchini Bake with Feta and Thyme is a recipe I came up with when I had a big surplus of zucchini from the garden, but the good news is that this recipe can easily be made with zucchini and yellow squash from the store or farmers market too. And when you still have zucchini but the weather is getting colder, it’s time for baked zucchini recipes, right? So I am featuring this for Friday Favorites today to entice you to try it!

I consider this to be a vegetable side dish, but with the protein from a couple of eggs and the feta cheese, it could easily be a meatless main dish too. And a few years ago I realized this is one of the Top Ten Low-Carb Zucchini Recipes on Kalyn’s Kitchen!

What ingredients do you need for this recipe?

  • yellow or green summer squash
  • olive oil
  • Minced Garlic (affiliate link)
  • fresh thyme leaves or Dried Thyme (affiliate link)
  • eggs
  • sour cream
  • crumbled Feta
  • grated Parmesan cheese
  • fresh lemon juice, I used my fresh-frozen lemon juice
  • salt and fresh ground black pepper to taste

What other cheese can you use?

If you’re not a fan of Feta you can make this dish with most any creamy white cheese like goat cheese, Cotija, Queso Blanco, or ricotta. Firmer white cheese that melt well will also work like Mozzarella, Monterey Jack, or Gruyere.

Can you use other herbs besides thyme?

I think other herbs would work fine in this recipe, especially basil or parsley.

What Size Baking Dish Did I Use?

I originally made this in a deep two-quart casserole dish, but I liked it a bit better in the 2-Quart glass rectangular casserole dish (affiliate link) I used in these photos. Having a dish with a little more surface area let more of the zucchini and yellow squash peek out, and I liked the way it browned on the top a little better.

How to make Zucchini Bake with Feta and Thyme:

(Scroll down for complete recipe with nutritional information.)

  1. Trim the squash, cut in half lengthwise, then make half-moon slices about 1/4 inch thick. I used a Mandoline Slicer (affiliate link) with the 7mm blade, but you can easily cut it with a knife.
  2. Heat olive oil, add the Minced Garlic (affiliate link) and fresh or Dried Thyme (affiliate link) and cook about 45 seconds.
  3. Then add the squash and cook about 4 minutes, turning a few times.
  4. Put half of  the partly-cooked squash into the casserole dish that you sprayed with non-stick spray and season with fresh-ground black pepper and a little salt.
  5. While squash cooks, break eggs into a bowl or a large measuring cup and beat until the yolks and whites are well combined. Stir in sour cream, Feta, Parmesan, and lemon juice.
  6. Spread half that mixture over the squash in the casserole dish, add the rest of the squash, season the second layer, and cover with the rest of the Feta mixture.
  7. Add optional crumbled Feta on top if using.
  8. Bake in a preheated 375F/ oven for 40-45 minutes, until the mixture is bubbling and slightly browned on top.
  9. Serve hot and enjoy! This will keep in the fridge for a few days, but like everything with zucchini it’s probably best freshly made.

Zucchini Bake with Feta and Thyme

Prep Time 10 minutes
Cook Time 50 minutes
Total Time 1 hour

This low-carb Zucchini Bake with Feta and Thyme is a delicious side dish any time; but especially when you have a surplus of zucchini from the garden.

Ingredients

  • 4 medium-sized yellow or green summer squash (see notes)
  • 1 T olive oil
  • 1 T minced garlic
  • 2 T fresh thyme leaves or 1 T dried thyme (or less if you’re not that fond of thyme)
  • 2 large eggs
  • 1/3 cup sour cream
  • 1 cup crumbled Feta, plus a few tablespoon more for the top if desired
  • 2 T grated Parmesan cheese
  • 1 T lemon juice
  • salt and fresh ground black pepper to taste

Instructions

  1. Preheat oven to 375F/190C. Spray a 2-Quart glass rectangular casserole dish (affiliate link) or any 2 quart casserole dish with non-stick spray or olive oil.
  2. Wash and dry squash, then cut off stem and blossom end and discard.
  3. Cut squash lengthwise in half, then slice into half-moon slices about 1/4 inch thick. I used a Mandoline Slicer (affiliate link) with the 7mm blade to get nice even slices, but you can use a knife.)
  4. Heat olive oil in large non-stick frying pan, add garlic and thyme leaves and cook about 45 seconds over medium-high heat (just long enough to season the oil, don’t let the garlic brown.)
  5. Add squash slices and cook about 4 minutes, turning a few times. Squash should be barely starting to soften.
  6. While squash cooks, break eggs into a small bowl or glass measuring cup and beat until egg yolks and whites are combined.
  7. Stir in sour cream, Feta, Parmesan, and lemon juice.
  8. Layer half the squash in the dish, then season with salt and fresh ground black pepper. (Remember the Feta is salty, so it won’t need a lot of salt.)
  9. Pour over half the egg-feta mixture and use the back of a spoon or a rubber scraper to spread it over the squash.
  10. Repeat with another layer of squash, seasoning again and covering with the rest of the Feta-egg mixture.
  11. Sprinkle a few tablespoons of crumbled Feta over the top if desired.
  12. Bake at 375F/190C for 40-45 minutes, or until the mixture is bubbling, slightly set, and top if lightly browned.
  13. Serve hot.

Notes

You need about 8 cups of sliced summer squash or zucchini; use any mixture of colors you prefer. This will keep in the fridge for a day or two, although it’s best freshly made. For best results, I recommend reheating in a toaster oven. Do not freeze.
