Recent black comedy about dinner party turned to murder

I watched this movie recently, let’s say in the past two years, on Netflix, I believe. Now I can’t find it anymore. The basic plot is: a woman invites friends and acquaintances to a dinner party. The guests arrive one by one and she proceeds to murder each one of them. Or did she?

I think it’s a recent movie, made probably in the past 10 years or so. Indie type, no major actor, as far as I remember.
