INGREDIENTS

  • 1½ lbs ground beef
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 cup breadcrumbs
  • 1 large egg
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon thyme leaves
  • 1 teaspoon rosemary, finely chopped
  • 1 cup french onion soup, condensed
  • ½ cup grated Parmesan cheese
  • Salt and pepper to taste

For Truffle Mashed Potatoes:

  • 2 lbs russet potatoes, peeled and cubed
  • 4 tablespoons unsalted butter
  • ¼ cup heavy cream
  • 2 tablespoons truffle oil
  • Salt and pepper to taste
  • 1 tablespoon chives, finely chopped

DIRECTIONS

  • Step No.1: Prepare the Meatloaf Mixture
    Preheat your oven to 375°F (190°C). In a pan, heat olive oil over medium heat, and sauté the diced onion and garlic until softened and caramelized.

  • Let them cool slightly before mixing them with the ground beef, breadcrumbs, egg, Worcestershire sauce, thyme, rosemary, and French onion soup. Season with salt and pepper.

  • Step No.2: Form the Meatloaf and Bake
    Transfer the meat mixture into a greased loaf pan and form it into a loaf shape. Top with grated Parmesan cheese.

  • Bake for 45-50 minutes, or until the meatloaf is fully cooked through, and a meat thermometer reads 160°F (71°C).

  • Step No.3: Make the Truffle Mashed Potatoes
    While the meatloaf bakes, boil the peeled and cubed potatoes in a large pot of salted water for 15-20 minutes, or until tender.

  • Drain and return to the pot. Mash the potatoes with butter, heavy cream, truffle oil, and season with salt and pepper. Stir in chopped chives for a fresh finish.

  • Step No.4: Serve and Enjoy
    Once the meatloaf is done, let it rest for 5 minutes before slicing. Serve the meatloaf alongside the creamy truffle mashed potatoes and garnish with additional chives, if desired.

TIPS FOR SUCCESS

  • Caramelize the Onions Well: Take the time to caramelize the onions fully to bring out their natural sweetness and deepen the flavor of the meatloaf.

  • Use Fresh Herbs: Fresh thyme and rosemary add a vibrant, fragrant note to the meatloaf. You can also experiment with other herbs.

  • Rest the Meatloaf: Let the meatloaf rest for a few minutes after baking to make slicing easier and avoid the juices spilling out.

  • Adjust Truffle Oil: If you’re new to truffle oil, start with a little and adjust to taste. It’s potent, so a little goes a long way.

  • Don’t Overmix the Meatloaf: Mix the meatloaf just until combined to avoid it becoming too dense.

  • Boil Potatoes Until Tender: Ensure the potatoes are soft and easily mashable before proceeding with the mashed potato mixture.

  • Use a Loaf Pan: A loaf pan helps the meatloaf cook evenly and maintain its shape, ensuring a perfect slice every time.

VARIATIONS

  • Ground Turkey Meatloaf: For a lighter version, substitute the beef with ground turkey or chicken for a leaner protein option.

  • Add Cheese to the Meatloaf: Incorporate some shredded cheddar or mozzarella cheese into the meatloaf for an extra creamy, cheesy bite.

  • Sautéed Mushrooms: Add sautéed mushrooms to the meatloaf mixture for an earthy, umami flavor that complements the French onion base.

  • vegan diet Mashed Potatoes: Replace the butter and cream with plant-based alternatives, such as olive oil and coconut cream, for a vegan twist.

  • Mashed Sweet Potatoes: Try substituting regular potatoes with mashed sweet potatoes for a sweeter and more colorful side dish.

  • Truffle Parmesan Crust: Top the meatloaf with a layer of Parmesan cheese and a drizzle of truffle oil before baking for a crispy, flavorful crust.

  • Add Bacon: For extra richness, crumble cooked bacon into the meatloaf mixture for added smokiness and flavor.

About Sana Umer

I'm Sana Umer — the home cook behind every recipe on For Foodie Friends. I'm a Pakistani-American mom of two based in the US, and I've been cooking seriously for about a decade now, mostly because feeding a family every day is the fastest way to learn how to actually cook.

I'm completely self-taught. I learned by watching my mother in Pakistan, by burning a lot of food in my early years, and by paying attention to which recipes worked and which ones needed fixing. I don't specialize in just one cuisine — I cook the Pakistani dishes I grew up with, the American desserts my kids request, weeknight dinners, holiday roasts, and everything in between.

Every recipe is personally tested in my own kitchen, every word is written by me, and every photo is taken of food I actually made.

Hi, I'm Sana Umer — the home cook, recipe tester, and writer behind For Foodie Friends.

I'm a Pakistani-American mom based in the US. I learned to cook in two kitchens — my mother's in Pakistan, where I grew up watching whole spices bloom in oil, and my own kitchen now, where I cook for my husband and kids.

Every recipe on this site has been tested in my own kitchen, often more times than I'd like to admit, before it ever made it here. I cook a little bit of everything: the Pakistani comfort food I grew up with, the American desserts my kids beg for, weeknight dinners that need to come together fast, and the holiday spreads that take all day.

If a recipe is on this site, it earned its place. No ghostwriters, no AI shortcuts, no copy-paste from somewhere else — just real recipes from a real kitchen, written to actually work the first time you make them.

Welcome to my corner of the internet.

— Sana
