Do you ever just wish dinner would take care of itself?
For me, the fourth quarter of the year always starts off with a lot of craziness. Whether it’s prepping for the busy holiday season or simply trying to get ahead to prepare for time off in the coming months, there seems to be so much more to do.
By the time I log off my computer, feed the dogs, and finish up my workout for the day, I am BEAT.
The exhaustion is so real, my friends. I just want to collapse into a heap on the couch. But then, I have to start thinking about dinner.
At that point, I just really want to have food delivered, or have magic fairies come in to make my dinner (as well as finish up all the dishes, clean my house, and rub my feet, since we are on the subject…).
Without fail, one-pan dishes are the one thing I turn to on these kinds of days.
Frequently, a one-pan meal implies a skillet or something made over the stove where you have to do some actual tending to the recipe.
Instead, this is a one-pan meal that requires nothing but simple roasting.
Seriously, that’s it.
One of our favorite cooking hacks is the one-pan meal. We love it for chicken, sausage, and so many more meals if we are in need for a quick meal with an even quicker clean-up.
For this recipe, you start with marinating a pork loin in a delicious and flavorful balsamic and Dijon mixture that’s enhanced with salt, pepper, and freshly chopped rosemary. It’s bright and bold, making it a fantastic centerpiece to any fall dinner table.
It’s so easy to make the marinade and stick it in the bag with the pork that’s been dotted with slices of garlic cloves. All you have to do is leave it in the refrigerator, and by the time you are done with work, it’s ready to be added to the pan with the rest of the ingredients.
The best part is, you can even prep this recipe far in advance. I love to get a fresh pork loin from the butcher, add it to a bag with the marinade, and vacuum seal the whole thing. You can then stick it in the freezer, and the protein is ready to go.
Simply let the pork thaw and it will be ready to cook up with the vegetables, just like that.
The pork loin is surrounded by seasonal vegetables, including sweet potatoes, red onion, and carrots. These hearty vegetables are the ideal mix to serve alongside the pork, as they have a good flavor, but won’t overpower the white meat.
It’s similar to what we use with our maple-glazed roast pork recipe. A medley of root veggies balances the meaty main without competing with it.
It’s such an easy dish to pull together, and once the simple prep work is complete, it only takes about 45 minutes in the oven, freeing you up to do something else while it roasts.
Do you know what that means?!
It means you can sit back and relax while dinner is coming together. Whether you love to read or you simply want to sit and watch an episode of your favorite show, you can do just that while dinner is coming along merrily in the oven.
At the end of a long day, not only do you need that ideal meal, you need that time to yourself to decompress before sitting down to enjoy it. Do yourself a favor, and try this for dinner on your next busy weekday.

Cooking By the Numbers…
Step 1 – Slice Garlic, Chop Rosemary, and Measure Marinade Ingredients
Thinly slice the garlic cloves. You should have 10 slices of garlic total. Set aside.
Remove rosemary leaves from the stem and chop until you have 1 teaspoonful to use in the recipe.
Measure Dijon mustard, balsamic vinegar, salt, and pepper.
I prefer to use freshly ground black pepper, since it offers the best flavor. If you don’t have a set already, check out our review of the best salt and pepper mills! They’re a great investment that I’m thankful for every time I cook.
Step 2 – Marinate Pork Loin
Lay the pork tenderloin out on a clean cutting board, and use the end of your knife to cut 10 1-inch slits in the pork loin about 1/4-1/2 inch deep (I prefer to use a boning knife for this type of work). Make sure they are evenly spaced from one end to the other, cut parallel to each other across the width of the meat.
Insert one slice of garlic into each slit, and gently place the pork into a zip-top plastic bag.
Combine the mustard, vinegar, rosemary, salt, and pepper in a small bowl, and whisk together. Add the marinade to the bag, seal it, and gently rub the pork with the mixture.
Refrigerate for 4 hours, or overnight.
Step 3 – Prepare Vegetables
When you are ready to cook, preheat the oven to 350˚F.
While the oven is preheating, wash and peel the vegetables. Cut the sweet potato into 1-inch chunks. Slice the carrots into thick rounds. Slice the red onion into 1-inch pieces. Set all of the vegetables aside in a medium bowl, and stir to combine and separate the onion.
Remove pork from the bag and place in a shallow baking dish. Add the vegetables around the pork loin.
Step 4 – Bake
Bake for 45 minutes, or until the thickest part of the pork registers 160˚F in the center on an instant read thermometer.
Let the pork rest for 5 minutes before slicing and serving with vegetables.
How Long Is the Ideal Time to Marinate the Meat?
In the recipe, you will see that you can marinate the loin from anywhere in between 4 hours to overnight. Of course, I think any time that you can marinate pork for longer than the minimum is best.
I personally aim to to marinate the pork as long as possible. The longer the better, because the more time the meat has to absorb all those yummy flavors, the better it will taste when you cook it. Marinades also help to add moisture, and tenderize meat.
if you can, marinate the night before you plan to cook it. You can even make it in the morning before you head to work so when you get home, you simply have to prep the vegetables and add everything to the baking dish.
