Ingredients You’ll Need

For the Meatloaf

• 1 ½ lbs lean ground beef or turkey (90–93%) – Leaner meat cuts down fat but keeps flavor.
• 1 large egg – Helps bind everything together.
• 1 small onion, finely diced – Adds moisture and sweetness.
• 2 cloves garlic, minced – For savory depth.
• ½ cup old-fashioned oats – A healthy, fiber-rich alternative to breadcrumbs.
• ¼ cup milk or unsweetened almond milk – Softens the oats for a tender loaf.
• 2 tbsp tomato paste – Adds umami flavor.
• 1 tbsp Worcestershire sauce – Enhances meaty flavor.
• 1 tsp Italian seasoning
• 1 tsp salt
• ½ tsp black pepper

For the Glaze

• ¼ cup ketchup
• 1 tbsp honey or maple syrup
• 1 tsp Dijon mustard
  Optional but adds that perfect sweet-savory tangy finish.

For the Protein-Packed Mashed Potatoes

• 2 lbs Yukon Gold or Russet potatoes, peeled and cubed
• ½ cup plain Greek yogurt (2% or nonfat) – Adds creaminess and protein.
• 2 tbsp olive oil or ghee – For richness.
• ½ cup warm milk (dairy or non-dairy)
• ½ tsp salt, or to taste
• ¼ tsp garlic powder (optional)
• Chopped chives or parsley for garnish

💡 Tip: Yukon Golds make the creamiest mash, but Russets give that fluffy, old-school diner texture. Use what you love!

Step-by-Step Instructions

Step 1: Prep and Preheat

Preheat your oven to 375°F (190°C).
Line a loaf pan with parchment paper or lightly grease it to make removal easy later.

Step 2: Mix the Meatloaf

1. In a large bowl, combine ground beef, oats, milk, egg, onion, garlic, tomato paste, Worcestershire sauce, Italian seasoning, salt, and pepper.
2. Use your hands (or a spatula) to gently mix until just combined.

👩‍🍳 Don’t overmix! It can make your meatloaf dense. Mix just until everything looks evenly combined.

Step 3: Shape and Glaze

1. Transfer the mixture into your prepared loaf pan, pressing lightly to shape.
2. In a small bowl, whisk together ketchup, honey, and Dijon mustard.
3. Spread half the glaze over the top before baking. Reserve the rest for later.

Step 4: Bake

Bake uncovered for 40 minutes, then brush on the remaining glaze.
Continue baking another 10–15 minutes, or until the internal temperature reaches 160°F (71°C).

Let the meatloaf rest for 10 minutes before slicing — this helps keep it juicy and tender.

Step 5: Make the Mashed Potatoes

1. While the meatloaf bakes, place peeled and cubed potatoes in a large pot and cover with cold water.
2. Bring to a boil and cook for 12–15 minutes, until fork-tender.
3. Drain well and return to the pot.
4. Add Greek yogurt, olive oil, milk, salt, and garlic powder.
5. Mash until smooth and creamy. Adjust consistency with more milk if needed.

🥣 Pro Tip: For ultra-smooth potatoes, use a potato ricer or hand mixer — but avoid overmixing to prevent gumminess.

Step 6: Serve and Enjoy

Slice your healthy meatloaf, spoon creamy protein-packed mashed potatoes alongside, and garnish with a sprinkle of fresh herbs.

Serve warm with a side of green beans, roasted broccoli, or a crisp salad for a perfectly balanced meal.

Pro Tips for Success

1. Don’t Overmix the Meat

Overmixing can make the meatloaf dense. Mix until just combined — a light hand gives you a tender result.

2. Soften Oats Beforehand

Letting the oats soak in milk helps mimic the softness of breadcrumbs and ensures moisture.

3. Rest Before Slicing

Always let the loaf rest at least 10 minutes after baking. It locks in juices and makes slicing easier.

4. Add a Veggie Boost

Grate in a small carrot or zucchini for extra nutrients and natural sweetness.

5. Use Greek Yogurt Wisely

Plain Greek yogurt keeps your mash creamy and adds extra protein without heaviness.

6. Double the Glaze

If you’re a sauce lover, make extra glaze for serving — it’s that good!

Healthy Swaps & Variations

Make It Gluten-Free

Use certified gluten-free oats or almond flour instead of regular oats.

Go Dairy-Free

Swap milk with almond milk and Greek yogurt with a plant-based yogurt alternative.

Low-Carb Option

Replace mashed potatoes with cauliflower mash or turnip mash for fewer carbs.

Vegetarian Twist

Use cooked lentils or plant-based ground “meat” for the loaf and vegetable broth for the mash.

Boost the Protein Even More

Add a scoop of unflavored whey or pea protein powder to the mashed potatoes (yes, really!) — it blends seamlessly.

Serving Suggestions
