    FYI, it is NOT dairy free if it contains butter and cheese...

      FYI, read the post and you'll see that there's an entire section about how to make this recipe dairy-free. Would have been quicker than leaving a rude comment.

    Definitely making this again. Made a lifestyle change where *most* keto diets fit my need. This was a great find. Couple subs due to availability: shallots instead of onion and Trader Joe’s Blanc de Blanc for the white wine. No cheese bc I’m dairy-free. Had some cold shrimp left over from last night ‘s cocktail app and this really moved the leftovers. *chef kiss*
