Ingredients for Savory French Onion Meatloaf with Truffle Mashed Potatoes

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 lb ground beef
1 cup breadcrumbs
1/2 cup milk
1 egg
1 onion, sliced
2 tbsp olive oil
1 tbsp Worcestershire sauce
Salt and pepper to taste
2 lbs potatoes, peeled and cubed
1/4 cup butter
1/4 cup cream
2 tbsp truffle oil

How to Prepare Savory French Onion Meatloaf with Truffle Mashed Potatoes

First things first, preheat your oven to 350°F (175°C). This ensures that your meatloaf gets that perfect cook all the way through.
Now, grab a skillet and heat up the olive oil over medium heat. Toss in your sliced onion and caramelize those beauties until they turn golden brown and sweet. This usually takes about 10-15 minutes, and trust me, the smell will be divine!
While the onions are doing their thing, let’s get that meatloaf mixture ready. In a large mixing bowl, combine the ground beef, breadcrumbs, milk, egg, Worcestershire sauce, and a generous sprinkle of salt and pepper. Yes, don’t be shy with the seasoning—this is where the flavor starts!
Once your onions are caramelized, take half of them and fold them into the meat mixture. This is where the magic happens! Mix until everything is just combined; you don’t want to overwork the meat.
Shape your mixture into a loaf and place it in a baking dish. Make sure it’s nice and compact, but don’t stress if it’s not perfect—it’s going to taste amazing regardless!
Now, take the remaining caramelized onions and pile them on top of the meatloaf. This adds a delicious layer that’s just irresistible.
Slide that baking dish into your preheated oven and let it bake for about 1 hour. You’ll know it’s ready when the internal temperature reaches 160°F (70°C) and it’s beautifully browned on top.
While the meatloaf is baking, let’s work on those truffle mashed potatoes! Peel and cube the potatoes, then boil them in salted water until they’re fork-tender, which should take around 15-20 minutes.
Drain the potatoes and return them to the pot. Add in the butter, cream, and truffle oil. Mash them until they’re smooth and creamy. Taste and adjust the seasoning if needed. Oh, the aroma of truffle will fill your kitchen!
Once your meatloaf is out of the oven, let it rest for about 10 minutes before slicing. This is crucial—it helps keep all those juices in!
Serve up your savory French onion meatloaf alongside those luxurious truffle mashed potatoes, and prepare for some serious comfort food bliss. Enjoy!

Tips for Success

Alright, let’s make sure you nail this savory French onion meatloaf with truffle mashed potatoes! Here are my top tips for success:

Season generously: Don’t be shy with the salt and pepper! The seasoning is crucial for bringing out the flavors in both the meatloaf and the mashed potatoes. Taste as you go and adjust to your liking!
Caramelizing onions: Patience is key! Cook those onions over medium heat, stirring occasionally. If you crank the heat up too high, they might burn instead of caramelizing. You want them to be golden, sweet, and super fragrant—trust me, it’s worth the wait!
Meat mixture: Don’t overmix! When combining the meat with the other ingredients, mix just until everything is combined. Overworking can lead to a dense meatloaf, and we want it tender and juicy!
Rest the meatloaf: After baking, let your meatloaf rest for about 10 minutes before slicing. This allows the juices to redistribute, keeping every bite moist and flavorful.
Truffle oil: A little goes a long way! Start with 2 tablespoons in your mashed potatoes, and feel free to adjust based on your taste preferences. It can be quite potent, and you want that luxurious truffle flavor without it being overwhelming.
Potato texture: For the fluffiest truffle mashed potatoes, make sure to mash them while they’re still hot. And if you like a bit of texture, you can leave some lumps—just be sure to give them a good mix with the butter and cream.

Follow these tips, and you’ll have a savory French onion meatloaf with truffle mashed potatoes that’ll have everyone coming back for more!

Variations of Savory French Onion Meatloaf

If you’re feeling adventurous or just want to mix things up a bit, here are some fun variations for your savory French onion meatloaf and truffle mashed potatoes!

Ground turkey or chicken: Swap out the ground beef for ground turkey or chicken for a lighter version. You’ll still get that delicious flavor, and it’s a great way to change things up!
Cheesy goodness: Add a cup of shredded cheese—like cheddar or mozzarella—into the meat mixture for an extra gooey surprise. You can also sprinkle some cheese on top before the final few minutes of baking for a bubbly, golden finish.
Mix in veggies: Sneak in some finely diced veggies like bell peppers, carrots, or mushrooms into the meatloaf for added nutrition and flavor. It’s a wonderful way to get some more veggies into your meal!
Herbs and spices: Experiment with your favorite herbs! Fresh parsley, thyme, or even a pinch of rosemary can elevate the flavor even more. Just remember to balance it out with the sweetness of the onions.
Mushroom truffle mashed potatoes: For a twist on the truffle mashed potatoes, fold in some sautéed mushrooms. They add a lovely earthy flavor that complements the truffle perfectly.
Different oils: If truffle oil isn’t your thing or you want to change the flavor profile, try using garlic-infused olive oil or even a hint of rosemary oil in your mashed potatoes for a unique taste.
Sweet potato mash: For a healthier alternative, swap the regular potatoes with sweet potatoes. They’ll give a lovely sweetness and vibrant color, plus they pair wonderfully with the savory meatloaf!

So, don’t be afraid to get creative! These variations can help keep your savory French onion meatloaf and truffle mashed potatoes exciting every time you whip them up!

Storage & Reheating Instructions

So, you’ve got some leftovers of that delicious savory French onion meatloaf with truffle mashed potatoes? Lucky you! Here’s how to store them properly so you can enjoy every last bite.

First off, let the meatloaf cool completely before you store it. This prevents condensation from forming and keeps it from getting soggy. Once it’s cooled, wrap the meatloaf tightly in plastic wrap or aluminum foil, or you can pop it into an airtight container. It’ll keep well in the fridge for up to 4 days. Just make sure to label it with the date so you don’t forget!

As for the truffle mashed potatoes, you can store them in a separate airtight container in the fridge for about 3 days. If they seem a bit dry when you’re ready to eat them again, don’t worry! Just add a splash of cream or milk as you reheat them to bring back that creamy texture.

Now, when it’s time to enjoy those leftovers, here’s how I like to reheat them:

Oven method: Preheat your oven to 350°F (175°C). Place the meatloaf in an oven-safe dish and cover it with foil to keep it moist. Heat for about 20-30 minutes, or until warmed through. For the last few minutes, you can remove the foil to get that top nice and crispy again!
Microwave method: If you’re in a hurry, the microwave works just fine. Slice the meatloaf and place it on a microwave-safe plate. Cover it with a damp paper towel to keep it from drying out. Heat in 1-minute intervals until warmed through, checking often. For the mashed potatoes, put them in a microwave-safe bowl, cover, and heat in 30-second intervals, stirring in between.
Stovetop method: For the mashed potatoes, you can also reheat them in a small saucepan over low heat. Stir in a bit of cream or milk as you warm them to help get that creamy consistency back!

With these storage and reheating tips, you’ll be ready to enjoy your savory French onion meatloaf with truffle mashed potatoes just as much the next day! Happy eating!

FAQ About Savory French Onion Meatloaf with Truffle Mashed Potatoes

Absolutely! Ground turkey, chicken, or even a mix of ground meats would work wonderfully. Just remember that different meats might change the flavor and texture a bit, but they’ll still be delicious!

What can I substitute for truffle oil?
If truffle oil isn’t your thing, you can use garlic-infused olive oil or a bit of rosemary oil for a different flavor profile. It won’t be the same luxurious taste, but it’s still tasty!

How do I know when the meatloaf is done?
The best way to check is by using a meat thermometer. You want the internal temperature to reach 160°F (70°C). If you don’t have a thermometer, you can cut into the meatloaf; it should be no longer pink in the center and the juices should run clear.

Absolutely! You can prepare the meatloaf mixture and shape it into a loaf, then cover and refrigerate it for up to 24 hours before baking. Just add a few extra minutes to the cooking time if it’s coming straight from the fridge.

What’s the best way to store leftovers?
Let your meatloaf cool completely, then wrap it tightly in plastic wrap or aluminum foil, or store it in an airtight container in the fridge. It should last for about 4 days. For the truffle mashed potatoes, store them separately in an airtight container for about 3 days.

Can I freeze the meatloaf?
Yes, you can definitely freeze the meatloaf! Wrap it tightly in plastic wrap and then aluminum foil, or place it in a freezer-safe container. It should keep well for up to 3 months. Thaw it in the fridge before reheating.

What’s a good side dish to serve with this meal?
I recommend pairing it with garlic green beans, roasted Brussels sprouts, or a simple garden salad. These sides add a refreshing contrast to the rich flavors of the meatloaf and mashed potatoes!

How can I make the mashed potatoes creamier?
To achieve creamier mashed potatoes, make sure to mash them while they’re still hot. Adding a splash more cream or milk, and butter will also help get that silky texture you’re looking for!

Can I make this recipe gluten-free?
Yes! Just use gluten-free breadcrumbs in place of regular ones. The rest of the ingredients should be gluten-free as well, but always double-check labels to be sure.
