Full Recipe 

Ingredients

• ½ cup (65 g) all-purpose flour

• 1 tsp baking powder

• ½ tsp salt

• 2 tbsp cold butter

• 2 large eggs

• ½ cup (120 ml) milk

• ½ tbsp butter + ½ tbsp olive oil (for sautéing)

• 2 shallots (or 1 medium yellow onion), finely chopped

• 1 lb (450 g) lean ground beef (93% lean / 7% fat)

• ½ tsp taco seasoning (or more to taste)

• Freshly ground black pepper, to taste

• Optional: ½ cup grated cheese (cheddar or mozzarella) for topping

• Optional garnish: chopped parsley, cilantro, or green onions

Cooking Directions

1. Prepare the dry mixture: In a mixing bowl, whisk together the flour, baking powder, and salt. Using your fingertips, rub in the cold butter until the mixture resembles fine crumbs.

2. Make the batter: Crack the eggs into the dry mixture, pour in the milk, and whisk until a smooth, lump-free batter forms. Set aside to rest while you cook the beef.

3. Cook the aromatics: In a large ovenproof skillet, heat ½ tbsp butter and ½ tbsp olive oil over medium heat. Add the chopped shallots or onion and cook for 3–4 minutes until softened and lightly golden.

4. Brown the beef: Add the ground beef to the skillet, breaking it apart with a spatula. Cook until browned all over, about 6–8 minutes. Stir in the taco seasoning and season with black pepper. Mix well so the flavors meld.

5. Assemble the skillet bake: Spread the beef mixture evenly in the skillet. Pour the prepared batter over the top, making sure it coats the beef mixture evenly. If using cheese, sprinkle it generously over the batter.

6. Bake: Preheat the oven to 375 °F (190 °C). Transfer the skillet to the oven and bake for 25–30 minutes, or until the top is puffed, golden brown, and set in the center.

7. Rest & serve: Let the skillet bake rest for 5 minutes before slicing into wedges. Garnish with fresh herbs if desired and serve warm.

Why You’ll Love This Recipe

This skillet bake combines the comfort of a casserole with the ease of a one-pan dish. The beef provides rich, meaty flavor, the onions add sweetness, and the light batter topping ties everything together into a dish that’s warm, fluffy, and satisfying. Unlike many casseroles that can feel heavy, this one has a balance of textures—juicy beef underneath, crisp edges, and a soft interior topping. It’s also versatile enough to work for family dinners, meal prep, or even casual entertaining.

The Origins and Inspiration Behind the Dish

While this recipe doesn’t come from one specific culture, it draws inspiration from several comfort foods. The batter topping resembles a Yorkshire pudding, a beloved British side dish often paired with roast beef. Meanwhile, the seasoned ground beef nods to Tex-Mex flavors, thanks to the taco seasoning. When these two ideas meet, you get a dish that feels both familiar and new—perfect for anyone looking to experiment beyond traditional casseroles.

Ingredient Spotlight

• Flour & Eggs: The base of the batter creates that light, fluffy texture, almost like a savory pancake baked right on top of the beef.

• Ground Beef: Choosing lean beef keeps the dish hearty without being greasy. You can also swap it for turkey, chicken, or even plant-based mince.

• Taco Seasoning: A small amount goes a long way in infusing the dish with smoky, spiced warmth. You can use homemade seasoning for a cleaner, preservative-free option.

• Onions/Shallots: They bring out sweetness that balances the savory richness of the beef.

• Cheese (optional): Adds gooeyness and indulgence, especially if you love a golden, cheesy crust.

Storage and Reheating Tips

Leftovers store beautifully. Once cooled, transfer portions to an airtight container and refrigerate for up to 3 days. To reheat, warm slices in the oven at 350 °F (175 °C) for 10–12 minutes until heated through—this keeps the topping from getting soggy. Avoid microwaving unless you’re short on time, as it softens the crust. For longer storage, you can freeze baked portions individually wrapped in foil and stored in freezer bags for up to 2 months. Reheat directly from frozen at 180 °C (356 °F) for about 25 minutes.

Common Variations to Try

• Vegetable boost: Add diced bell peppers, mushrooms, or zucchini to the beef mixture for extra nutrients.

• Spicy version: Stir chopped jalapeños or a pinch of chili flakes into the filling.

• Cheesy deluxe: Double up on the cheese layer with mozzarella inside and cheddar on top.

• Different meats: Try ground turkey, lamb, or chicken as alternatives to beef.

• Mini bakes: Portion the batter and beef mixture into muffin tins for individual servings—perfect for packed lunches.

Pairing Recommendations

This skillet bake pairs wonderfully with a crisp green salad to cut through the richness. A tangy slaw with vinegar dressing also works beautifully. For something heartier, serve with roasted vegetables like carrots or Brussels sprouts. As for drinks, iced tea or a light lager balances the flavors nicely, while red wine lovers might enjoy a medium-bodied merlot alongside.

Health Benefits

While indulgent, this dish has a solid nutritional profile. The lean beef provides plenty of protein and iron, both essential for energy and muscle health. Eggs contribute additional protein plus vitamin B12. The flour and milk batter brings calcium, while onions deliver antioxidants and compounds that support heart health. If you add vegetables or herbs, you boost the fiber and vitamin content further.

With its fluffy crust, tender beef filling, and customizable flavors, it’s a recipe that fits into weeknight routines while also being impressive enough for guests.
