How to Make Maple Mustard Beef Tenderloin with Caramelized Onions

Step 1: Trim the Beef

Start by trimming any silver skin from your beef tenderloin. This helps ensure that your meat is tender and not chewy. Use a sharp boning knife to slide under the silver skin at one end. Pull it taut while running your knife along—it’s easier than it sounds! Discard any silver skin once done.

Step 2: Seasoning Time

In a small bowl, combine 1 ½ tsp kosher salt and ¼ tsp pepper with garlic powder, onion powder, dried thyme, paprika, and poultry seasoning. Rub this blend generously into both tenderloins. Let them sit for at least 45 minutes or up to several hours—this allows those flavors to soak in deeply. Make sure to take them out of the fridge half an hour before roasting so they can come up to room temperature.

Step 3: Caramelizing Onions

In a wide skillet over medium heat, melt together butter and 1 tbsp olive oil. Once melted, add all your thinly sliced onions along with a generous pinch of kosher salt. Cook them for about 3-4 minutes until they soften before reducing your heat to medium-low. Keep an eye on them as they cook low and slow; stirring regularly will help them caramelize evenly without sticking.

Step 4: Finish Cooking Onions

Let those onions work their magic over medium-low heat until they’re golden brown and incredibly fragrant—this step usually takes around 45 minutes. Don’t rush; patience is key! Once they’re perfect, transfer them to a baking dish and set aside.

Step 5: Prepping Your Oven

Preheat your oven to 400°F while you prepare your sauce mixture. In a small bowl, whisk together maple syrup, grainy mustard, minced garlic, balsamic vinegar, Worcestershire sauce, along with remaining salt and pepper.

Step 6: Searing the Beef

Heat up another skillet over high heat with the remaining olive oil. When hot enough, add your seasoned tenderloins and sear until golden brown on all sides—this locks in moisture and enhances flavor! Once seared perfectly all around, place them in the baking dish with those beautiful caramelized onions.

Step 7: Making Your Sauce

Now it’s time to deglaze! Pour in your beef broth into that hot skillet—use a wooden spoon to scrape up all those tasty brown bits left behind. Bring it back to simmering before adding in that lovely maple mustard mixture you prepared earlier. Cook for just about 3-4 minutes until slightly reduced before pouring over your tenderloins.

Step 8: Roasting

Roast that beauty in the oven for about 15-20 minutes until it reaches an internal temperature of 145°F. Once done cooking, transfer those tenderloins onto a cutting board and loosely tent them with foil—allowing them to rest is crucial as it keeps all those juicy flavors locked inside!

Step 9: Serving Up

Slice those tenderloins into medallions right before serving! Arrange caramelized onions on a platter first before placing those succulent slices on top. Drizzle any remaining pan juices over everything—trust me; this adds another layer of flavor that’s simply divine! This dish pairs wonderfully with parsnip and apple purée or any favorite side you love!

Enjoy every bite!

Pro Tips for Making Maple Mustard Beef Tenderloin with Caramelized Onions

Creating a delicious beef tenderloin might seem daunting, but with a few handy tips, you’ll be a pro in no time!

• Season well: A generous rub of spices not only adds flavor but also forms a savory crust during cooking. This enhances both the taste and texture of your tenderloin.

• Let it rest: After roasting, always let the meat rest before slicing. This allows the juices to redistribute throughout the meat, making each bite moist and flavorful.

• Watch the temperature: Use a meat thermometer to ensure your beef reaches the perfect doneness. This prevents overcooking and ensures that your tenderloin remains juicy.

• Caramelize slowly: Patience is key when caramelizing onions. Cooking them on low heat allows their natural sugars to develop beautifully, resulting in rich, sweet flavors that complement the beef perfectly.

• Make it ahead: If you’re short on time, you can prepare the caramelized onions in advance. They store well in the fridge and can save you precious minutes on meal day!
