I don’t need anyone to give me incentives to love pork more than I do… I mean… not only is pork delicious, but I have found it to be one of the EASIEST dishes to prepare.

Read: easy and delicious dinners make mama happy and when mama’s happy…

You catch my drift.

Plus, the weather is turning down the volume on the heat and during the cold months of the year everyone in the family loves the smell of a good hot meal in the oven. Or crock pot, but I’ll talk more about that crock pot later this month…

One of my favorite recipes (and by favorite I mean FAVORITE) I make that celebrates pork and makes mouths water is my Rosemary Garlic Roasted Pork Tenderloin. Pretty sure your mouth just watered. Serve it up with a baked sweet potato and you are almost willing to wave off Spring and Summer altogether.

I like to get my pork at Costco. Theirs is an offering of a variety of pork cuts at a great value. PLUS… I can also shop for all the equipment I need to make my holiday favorites!

But enough about my shopping habits – how about this amazing recipe?

You will need olive oil, rosemary, garlic, salt, pepper, and pork tenderloin.

I also like getting my pork at Costco because I get a lot. These pork tenderloins come in a two pack, and each pack has TWO tenderloins. I cook one package of two tenderloins right away, and freeze the other.

So. THE RECIPE… Take your rosemary and separate the leaves from the stems.


Chop up the rosemary and breathe deep… enjoy the delicious smell. Your nose will thank you.


Mince the garlic. I love my garlic press. I never use minced garlic from a jar, but you are more than welcome to do what works for you!

Add the chopped up rosemary, minced garlic, salt, and pepper to the olive oil.

And stir.

Spray a 9 x 13 glass dish with cooking spray and lay the tenderloins on the prepared dish. Then get a basting brush and brush that rosemary garlic goodness all over your pork tenderloins… not forgetting to take deep breaths so you don’t miss any chance to breathe in the fragrant rosemary!

Place the dish into your preheated to 400 degree oven. In about 30ish minutes (note: mine has never taken under 30 minutes) your masterpiece should reach it’s optimal temp — an internal temperature between 145°F (medium rare) and 160°F (medium), followed by a three-minute rest, using a digital thermometer to ensure accuracy.

Speaking of nailing it…

Surround your rosemary garlic oven roasted pork tenderloin with the most beautiful produce… I think sweet potatoes and broccoli are VERY beautiful. The sweetness of the sweet potato compliments the savory juices of the pork tenderloin LIKE A BOSS. The broccoli is green and that’s my favorite color and it is the MOST favorite veggie in my family so yeah… broccoli is definitely beautiful to me!
