Baked Artichoke Hearts Au Gratin with Green Onion, Parmesan, and Romano found on

There’s not many more days until you have to settle on the side dishes you’re cooking for Thanksgiving dinner, and to make it even harder, here’s another option I’m adding to the Thanksgiving ideas in my Holiday Recipes category! I tested several versions of this Artichoke Hearts Au Gratin and this version was the one that’s a keeper. I’m featuring this recipe for Friday Favorites this week to see if I can entice some of the artichoke fans to try it!

I used a combination of Parmesan and Pecorino-Romano cheese, but even if you only had Parmesan, I’m sure this would be delicious. And although I first tested this recipe with breadcrumbs, for a few years now I’ve been switching that out for Almond Flour for a low-carb and gluten-free version of this tasty dish.

What ingredients do you need? 

Can you use canned artichoke hearts?

I became enamored with canned Artichoke Hearts packed in water (affiliate link) when I was testing recipes for Air Fryer Artichoke Hearts! And as long as they’re drained well I think the canned ones will be great for this recipe.

What does Au Gratin mean?

Au Gratin means sprinkled with breadcrumbs or grated cheese, or both, and browned. In this recipe it works perfectly to switch out the small amount of breadcrumbs for almond flour mixed with cheese to make the au gratin topping low in carbs!

How to make Artichoke Hearts Au Gratin:

(Scroll down for complete recipe, including nutritional information.)

  1. I used frozen artichoke hearts, and the 12 oz. package I found at Smith’s in Salt Lake was just right for four servings.
  2. Thaw artichokes and then drain them well before you assemble the dish.
  3. Grease the gratin dishes with olive oil, then arrange artichoke hearts in a single layer. (I loved this in these two 7″ round gratin dishes, but I made one of my test versions in an 8.5 x 8.5 inch baking dish which also was fine.)
  4. Chop up the green part of 3 green onions and sprinkle over the artichoke hearts.
  5. Mix finely grated Parmesan and Romano with the almond flour, dried thyme, and dried oregano. (I only had the coarsely grated cheese, so I buzzed it in my mini-processor to make a more finely ground mixture.)
  6. Whisk together the mayo, lemon juice, lemon zest, and garlic puree. Then mix in 1/2 cup of the cheese mixture. (Set aside the other 1/2 cup of cheese mixture.)
  7. Spread that mixture over the top of the artichoke heart, using a rubber scraper. Cover with foil and bake at 325F/170C for about 30 minutes.
  8. Sprinkle the reserved cheese mixture over the top and bake about 25 minutes more.
  9. The Baked Artichoke Hearts Au Gratin are done when the top is lightly browned and mixture is hot clear through.
  10. (I haven’t tried baking this for a shorter time at a higher temperature but if anyone tries that I’d love to hear how it works.)

Baked Artichoke Hearts Au Gratin with Green Onion, Parmesan, Romano and almond flour replacing the breadcrumbs are a delicious low-carb side dish for any special meal.


  • one 12 oz. pkg. frozen artichoke hearts, thawed, drained, and larger ones cut in half
  • 1/4 cup green onions, very thinly sliced (see notes)
  • 2 tsp. olive oil
  • salt and fresh ground black pepper to taste
  • 1/4 cup almond flour
  • 1/3 cup grated Parmesan cheese
  • 1/3 cup grated Pecorino-Romano cheese
  • 1/2 tsp. dried thyme
  • 1/4 tsp. dried oregano
  • 1/3 cup mayo
  • 1 tsp. lemon zest (see notes)
  • 2 T lemon juice
  • 1/2 tsp. garlic puree


  1. Preheat oven to 325F/170C.
  2. Thaw artichoke hearts in the microwave if they’re still frozen, then drain well.
  3. Cut larger artichoke hearts in half lengthwise so they’re all the same size.
  4. Use olive oil to grease 2 small gratin dishes or 1 medium sized baking dish. (I made this in an 8.5 x 8.5 inch square baking dish and also in the 2 small 7 inch round gratin dishes in the photos.)
  5. Arrange artichoke hearts in a single layer in the oiled dish.
  6. Then sprinkle finely sliced green onions over the artichokes and season with salt and fresh ground black pepper.
  7. Mix together almond flour, grated Parmesan cheese, grated Pecorino-Romano cheese, and dried herbs. (If the cheese isn’t finely grated you might want to buzz it in a mini-processor for a minute or two like I did.)
  8. Whisk together the mayo, lemon juice, lemon zest, and garlic puree; then mix in 1/2 cup of the cheese mixture.
  9. Use a rubber scraper to spread this over the top of the artichoke hearts, setting aside the rest of the bread crumb/cheese mixture.
  10. Cover the dishes with foil and bake in 325F/170C oven for 30 minutes.
  11. Remove from oven and increase temperature to 375F/190C.
  12. Remove foil and sprinkle the remaining cheese mixture over the top of each dish.
  13. Put back into oven and bake about 25 minutes more, or until the topping is lightly browned, and the dish is hot clear through.
  14. Serve hot or warm and wait for compliments!


I haven't experimented with baking this for a shorter time at a higher temperature, but if anyone tries this I'd love to hear how it works!

I just used the green part of the green onion, but use the white part too if you prefer. Zest the lemon first, and then squeeze the juice. Almond flour (affiliate link) is pretty widely available in stores, but you can buy it at if you can't find any.

Artichoke hearts do have some carbs, but they are high in fiber which reduces the net carbs.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Switching to almond meal for a gluten-free and lower-carb option makes this dish better for low-carb diets, but artichokes do have some carbs to check the net carbs if you’re doing Keto. This is probably best as a “once in a while treat” for South Beach, due to the fat content, but it would be great for low-carb diet plans.
