Hola from Barcelona! ?

Today marks two weeks that we’ve been living in Spain, and — oh man, you guys — we are absolutelyย loving it. For a thousand reasons, this city just feels so magical…and exciting…and quirky, and delicious, and fun, andย nuanced, and richly diverse, and alive, and literally full of surprises around every corner we turn. And weย are soaking up every minute of it.

That said, at two weeks in,ย I feel like it’s a constant back-and-forthness each day between feeling like we’re just on vacation here…and feeling like we actuallyย live here. ?

Probably about half of the time, itย stillย just feels like we’re here on this extravagantย trip — wandering downย charming newย streets for the first time, Yelp-ing new restaurants to try,ย taking long walksย on the beach (omg, the beach!!), hearing different languages spoken around us all day long, freaking out over all of the adorable twinkly lights and banners strung everywhere you turn. But on the other hand, it’s kind of amazing how half of the time, this place is already totally starting to feel familiar. Like we really do live here! From waking up each morning in the same cute little apartment to the sound of our neighborhood pigeons, to knowing the twisty-turny routes to our favorite market and coffee shop and yoga studio and El Corte Inglรฉs now by heart, to speaking Spanish all day long, to getting a wave from Alejandro at the wine shop next door each time we take our dogs out for a walk. In two short weeks, it’s kind of amazing how natural this place already feels.

Without a doubt, though, we’ve agreed that are two things that make this place feel like we actually live here more than anything — having our pups here, andย cooking here.ย  I don’t know about you all, but there’s always been somethingย so grounding for me about going to the market, bringing home groceries, and actually cooking a homemade meal that always makes a new place feel more like home. And while our tiny kitchen here still onlyย boastsย theย single sautรฉ pan andย saucepan that it came with — plus an Instant Pot, which I’m thrilled to say just arrived from Spanish Amazon —ย Barclay and I have already had lots of fun cooking dates putting them to use.

One of our favorite recipes so far? This zesty and comforting Cajun Shrimp Alfredo Casserole.

Why Cajun, you ask?

Ha, well,ย on the day that we cooked this, we wentย grocery shopping at a cute little market nearby that was overflowing with colorful bell peppers, fresh shrimp, and — of course — rice galore. But when we got home, we realized that we still hadn’t purchased any spices for our kitchen yet here in Spain. ? Thankfully, I had packed a few of my favorites (that I thought might not be available here) in my suitcase to bring over from the States, including a trusty tin of Old Bay.

So…Cajun food it was!

Also, ha, our small sautรฉ pan that came with the apartment wasn’t quite big enough to holdย all of the rice and veggies and shrimp that we had prepared. So I whipped up a simple Cajun alfredo sauce, stirred everything together in a large baking dish, and popped it in the oven to cook a bit longer. Then once it was ready, we sprinkled it with lots of extra Parm and parsley and lemon juice. And sure enough, it ended up turning into a total comfort foodย win.

I mean, I don’t know how you can really go wrong here. Zesty shrimp and veggies, creamy (and lightened up) Cajun alfredo sauce, lots of hearty rice — win-win-win. ? PLUS, if you happen to be cooking for a crowd, this dish could be easily made a few hours ahead of time, then heated in the oven just before serving. And of course, if shrimp isn’t your thing, chicken and/or sausage would totally work here too.

So cheers to comfort food all around…wherever in the world it may find you.

Enjoy, everyone!

    This was delicious. Pre the comments, I added 5 mild Italian sausage links sliced and browned, 1/4 tsp garlic powder and 1 teaspoon smoked paprika.
