  1. Perfect. Absolutely perfect. I’ve made these three times and every time they are a ~hit~!!!

    I freeze mine (after they are assembled) and pop them in the oven right before the parteee <3 The easiest recipe to make your friends think that you are an expert chef.

    Also, I used this puff pastry recipe the most recent time I made them and they were the BEST they'd ever been!
    https://www.dessertfortwo.com/15-minute-puff-pastry/

  2. I have made this recipe exactly as described many times now and they never disappoint. For potlucks, game day eats or garden parties, these cheesy, creamy, savory sweet bites are always a hit! Thank you so much for the recipe. Please keep ’em coming!

  3. Is there another cheese I could substitute for feta cheese? I am having problems right now getting feta. I am in remote Alaska. When I did use feta the recipe was great. Thank you for the treats.

  4. I followed the recipe exactly as written except my mini muffin tins only made 24 instead of 30 tartlets. I froze them unbaked in the tins. I baked them right before I took them to a party and this worked out perfectly. They were a huge hit and were gobbled down within minutes!

  5. What does 3 ounces of feta look like? Is there another measure you can clarify? Maybe tablespoons? Just made the blueberry goat cheese ones. Have made several of your other recipes and always turn out great! Thanks!

  6. The Trader Joe’s ingredients say they use cream cheese. Is there a reason why you use sour cream? here is their posted ingredient list: INGREDIENTS
    Puff pastry (enriched wheat flour (Wheat Flour, malted barley flour, ascorbic acid [vitamin c as dough conditioner], Niacin, Folic Acid, reduced Iron, Thiamin Mononitrate, Riboflavin), water, butter, salt), cream cheese (pasteurized cultured cream, milk, natural acids, salt, xanthan gum, carob bean gum, guar gum), onion, feta cheese (pasteurized milk, salt, cheese culture, enzymes), egg, sugar, unsalted butter [milk].

    1. The reason I use sour cream instead is because cream cheese has very pronounced flavor and your bites will taste more like cream cheese than feta. Feta is so mild it can easily get lost and overpowered. You never know what type of cream cheese TJs is using (not like our store bought kind) and it’s not affecting the flavor profile as it would if we used it. Feel free to test it using cream cheese but don’t be surprised if it doesn’t taste like feta anymore. I stand by using sour cream for this recipe. I hope you enjoy them either way.

  7. Recipe sounds wonderful!

    Just to clarify, do I use 3 sheets of puff pastry total (1 on top of the other), then cut the block of puff pastry sheets into 30 squares?

    1. Sorry for the confusion. The puff pastry sheet is originally folded into thirds. You’ll want to completely unfold it and cut it into 30 squares (total). I hope this clears it up for you.

  8. These are my favorites at Trader Joe’s! Happy to have a homemade hack.

    I subbed 3% fat plain yogurt for the sour cream, and subbed sharp cheeses I had on hand instead of the feta. Tasted delicious! Only next time I will halve the butter, as the dough was soaked even after doubling the baking time. Regardless, super excited to make these again with this tweak.

    1. The sogginess you experienced was most likely from the substitution of 3% fat yogurt. Halving the butter may actually worsen the sogginess of the product. These types of substitutions rarely work well in recipes. Perhaps sticking to the recipe, and eating it in moderation would be a better choice.
