an easy shrimp scampi dinner

Two weeks ago, during my first-ever trip to Trader Joe’s, I picked up some incredibly tasty Argentinean red shrimp. We love shrimp dinners, but if you have a tight grocery budget (we do!), seafood purchases are a rare occurrence.

Trader Joe's brand precooked Argentinian Red Shrimp

Having the opportunity to splurge on delicious seafood, the menu plan included a recipe that allows the shrimp to be the star of the show.  The clear winner is a quick and easy shrimp scampi recipe!

I also make my own garlic butter for the shrimp scampi, saving big money over the premade variety.

How do you make garlic butter sauce for shrimp?

Making garlic butter to use for the easy shrimp scampi recipe is ridiculously simple! All you do is combine minced garlic or garlic powder with softened butter. Seriously, it’s that easy! As the butter melts in the pan, the minced garlic will cook.

To make the dish a little healthier, I serve it over spaghetti squash instead of pasta. By doing so, you will save over 200 calories per serving!

Is spaghetti squash low carb?

Not only is spaghetti squash low in carbs, but it is also keto friendly. One cup of plain, cooked spaghetti squash has 5 net carbs.

Another plus is that spaghetti squash is a home run with most kids. You will get veggies into their system, yet they will hardly notice a difference. It is a win-win for the parents! 🙂

How do you cook spaghetti squash?

To prepare spaghetti squash so that it comes out in long, spaghetti-like strands:

    1. Cut the squash in half across the middle, then use a spoon to scoop out the seeds and pulp. See photo above.
    2. Place the pieces of squash, flesh side down, into a microwave-safe casserole dish, adding about 1/8 cup of water to the dish. Cover the dish with plastic wrap, leaving a small corner open, for venting purposes.
    3. Microwave on high for 9-11 minutes, or until the skin of the squash is tender and can be pierced easily with a fork.

How to cook spaghetti squash in an oven

If you don’t want to microwave the squash, you can cook it in an oven. To do so, remove the seeds and pulp, then place the squash flesh side up on a baking sheet. Preheat the oven to 400 F., then roast the squash for about 40 minutes. To prevent it from browning too much, tent the squash with aluminum foil.

  1. After the squash has finished cooking, carefully remove the plastic wrap or aluminum foil. NOTE: Release it away from you, being mindful so as not to let the steam hit you in the face.  The squash will be VERY hot! Allow it to cool for a few minutes before removing the flesh from the skin.
  2. Use an oven mitt or pot holder to hold the squash in one hand. Using the other hand, hold a fork to pull the long strands of flesh from the skin.

 

While the spaghetti squash cooks, you will make the shrimp scampi.

When the scampi is ready, divide the spaghetti squash between two dinner plates. Ladle portions of shrimp over the squash. If desired, sprinkle some freshly chopped parsley and grated Parmesan cheese over the shrimp scampi. Serve and enjoy!

    1. I absolutely LOVE garlic. If i found a cereal that tasted good with it; you can guarantee I would be crushing it up to put in my milk! What is there NOT to love about garlic? So many options- fresh cloves, garlic salt, garlic paste, garlic powder, granulated garlic… you get where I’m going. The taste;- so savory. The smell of fresh garlic being roasted or sauteed- its like the aroma is dancing in the hairs of my nose. Talking about it just makes my mouth water! There are so many foods that need that little umph- thats when i go for the fresh head of garlic and chop it up nice and fine to add to the dish!

    2. There’s not much better than the combination of butter & garlic!!! I use Lia Marie’s every chance I get….:D Love the stuff!!!!!

    3. Shrimp, Garlic Butter, and Squash…..How can you go wrong with that? I try to put garlic in most of my meals.
