Recipe Box, Summer Squash Galette w/Tempura Onion Topping

I know I posted about zucchini earlier this month for Sneak a Zucchini on your Neighbor’s Porch Day, but this post is more about the onions than the zucchini

Thin delicate tempura battered fried onions…sigh…

I discovered how thinly you could slice onions with a spiralizer when I made Spiralized Onion & Potato Pie

I couldn’t wait to try frying  these thin slices of sweet onion

I found this simple 3 ingredient tempura batter here,  it’s just flour, water and egg whites

We had some for cocktail nibbles and then I saved the rest for topping the galette we were having for dinner

This recipe is a slight variation of Zucchini Garlic & Gruyere Galette

I cut the squash into slices with a spiralizer and let them drain on paper towels after salting

I promise I’m not trying to sell spiralizers, I just have been having so much fun with mine~

The secret to this galette is the roasted garlic spread on the bottom, and the real Parmigiano Reggiano cheese

So much irresistible flavor

You can skip the onion topping if desired, it’s delicious either way

  1. Jenna, what a beautiful dish! Squash is the summer vegetable that keeps on giving and what a wonderful recipe to still enjoy squash! Adding the onion rings on top is a win! Happy Thursday as we are feeling a touch of autumn this morning, I can’t wait!

    • Really? That is wonderful and actually I felt the same thing when I went outside on the porch at the beach this morning, it’s almost cool! I’m sure that will change later πŸ˜… Thanks Pam

  2. Linda says:

    Wonderful recipe Jenna. I don’t know how you do so much, but I love it! Have a fabulous weekend.

  3. I bet the cheese does make al the difference in the world! Yummy, Jenna!

  4. Yummy! I need to buy a spiralizer. My husband loves gadgets.
    Your galette is so tempting.

  5. So these onions are like the French’s Onions that come in a can…only fresher and better BECAUSE they’re fresh? Is the taste similar? This looks so easy, I’m thinking I may try making them to put on casseroles and salads!

    • Yes! You can add more seasoning like cayenne or garlic if you want to also~ I was excited to see that you enabled comments again on your cute cute summer party post, but I couldn’t ever find the place to comment? Anyway, I hope you’ll share your killer margarita recipe, or is it a secret?

  6. Can I have it for breakfast? Like now?
