And this. Creamy. Delicious. Heaven. Three of my favorite ingredients, asparagus, mushrooms, and Dijon mustard. In a dreamy sauce. Next time you make a fancy meal, serve this Asparagus Gratin on the side.
So, happy almost Easter to you! What do you do, if you celebrate, for your Easter dinner? Growing up, we had turkey. …Actually, Thanksgiving, Christmas, and Easter, we always had turkey. My grandmother (who is now 95, God love her) always made the same exact meal, no matter the holiday. And that was alright. Because what she made was sooo good.
Once I set out on my own (and learned to cook), I started mixing it up. Turkey for Thanksgiving. Roast for Christmas. Ham for Easter. Or something like that. And Green Bean Casserole, which is soooo good. So I guess this new recipe is in the spirit of the good old green bean casserole, only even better.
See, asparagus is my favorite veggie. I make it at least once a week, usually roasted in the oven with a little olive oil and seasoning. …But asparagus. Asparagus is delicious. And this was the first time I did up a little gratin with it. And it was just divine.
So, save this. Pin it, whatever. This asparagus casserole is the perfect side for your holiday table, celebratory dinner, or any special occasion. …or just because.
