Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 40 minutes
• Total Time: 50 minutes
• Servings: 4
• Dietary Type: Gluten-Free (naturally)

Ingredients

• ¾ – 1 lb pork tenderloin
• 2 tablespoons butter, divided
• 2 medium onions, sliced
• ½ teaspoon salt
• ¼ teaspoon ground black pepper
• 2 tablespoons sugar
• ¼ cup port wine or ¼ cup sweet sherry
• 2 tablespoons balsamic vinegar
• 1 cup fresh blueberries or 1 cup frozen blueberries
• 1 cup chopped cherry tomatoes

Equipment Needed

• Broiler
• Large Skillet
• Platter

Instructions

1. Preheat your broiler. Position a rack so the pork will be about 4-6 inches from the heat source.

2. Broil the pork tenderloin, turning it occasionally, until it’s cooked through. This should take approximately 20 minutes. Use a meat thermometer to ensure the internal temperature reaches 145°F (63°C) for medium doneness, followed by a 3-minute rest.

3. Once cooked, remove the pork tenderloin to a platter. Cover it loosely with foil to keep it warm while you prepare the sauce. This resting period allows the juices to redistribute, resulting in a more tender and flavorful final product.

4. Now, let’s make the sauce. In a large skillet, melt 2 tablespoons of butter over medium-high heat. Make sure the skillet is large enough to accommodate all the ingredients without overcrowding.

5. Add the sliced onions, salt, and ground black pepper to the melted butter. Cook, stirring occasionally, until the onions are golden and softened, about 10 minutes. Don’t rush this step; allowing the onions to develop their color and sweetness is crucial for the overall flavor of the sauce.

6. Sprinkle sugar over the golden onions. Continue cooking until the onions are caramelized, about 3 minutes longer. Keep a close eye on the onions at this stage to prevent them from burning. The sugar should melt and create a rich, glossy coating.

7. Pour in the port wine (or sweet sherry) and balsamic vinegar. Bring the mixture to a boil, scraping up any browned bits from the bottom of the skillet. These browned bits, known as fond, are packed with flavor and will add depth to your sauce.

8. Add the blueberries (fresh or frozen) and chopped cherry tomatoes to the skillet. Bring the sauce back to a boil, then remove it from the heat. The residual heat will gently soften the blueberries and tomatoes, releasing their juices and creating a vibrant, flavorful sauce.

9. Thinly slice the pork tenderloin against the grain. This helps to shorten the muscle fibers, making the pork more tender and easier to chew.

10. Serve the sliced pork immediately, generously spooning the blueberry-onion sauce over the top.

Expert Tips & Tricks

• Pork Doneness: Use a meat thermometer to ensure your pork is cooked to perfection. Insert the thermometer into the thickest part of the tenderloin, avoiding any bones.
• Caramelizing Onions: Low and slow is the key! Don’t try to rush the caramelization process. Patience will reward you with deeply flavorful, sweet onions. If they start to burn, reduce the heat slightly and add a tablespoon of water to deglaze the pan.
• Blueberry Burst: For an extra burst of flavor, reserve a handful of fresh blueberries and stir them into the sauce just before serving. This will provide a pop of freshness and visual appeal.
• Make-Ahead Tip: The blueberry-onion sauce can be made ahead of time and stored in the refrigerator for up to 2 days. Reheat gently before serving.

Serving & Storage Suggestions

Serve this Blueberry-Onion Sauced Pork Tenderloin immediately for the best flavor and texture. A side of roasted asparagus, wild rice pilaf, or creamy polenta would complement the dish beautifully.

Leftovers should be stored in an airtight container in the refrigerator. They will last for up to 3 days. To reheat, gently warm the pork and sauce in a skillet over medium heat, or microwave in short intervals, stirring occasionally, until heated through. Note that the pork may become slightly drier upon reheating.
