This Boursin Mashed Potato and Beef Casserole is my favorite comfort food when I'm in the mood for a casserole full of flavor. It's the perfect combination of tender green beans, spicy ground beef, and creamy mashed potatoes flavored with Boursin. And the best part? The whole family loves it!
Creamy Boursin Mashed Potato Bake with Beef
Cooking with children can be difficult at times. It is always a search for something that everyone likes. But every now and then, you make a dish that everyone likes. And this is such a recipe!
What makes this recipe special is the Boursin in the mashed potatoes. It gives a creamy taste that perfectly matches the hearty ground beef and green beans. And, of course, a crispy layer of breadcrumbs on top. That reminds me of the past when we often ate casseroles with breadcrumbs. This recipe is ideal for a cold day; you slide it in the oven, and after 20 minutes, you can enjoy it. It's exactly what you need after a busy day.
This casserole has everything you need without spending a long time in the kitchen. It's really something for those who like simple and tasty!
Ingredients
- Potatoes: Use a floury variety such as Russet, Yukon, Doré, King Edward, and Maris Piper. These are perfect for a soft, creamy purée.
- Vegetable stock: Adds extra flavor during cooking. You can use a stock cube or make your own vegetable stock.
- Boursin: Makes the mashed potatoes nice and creamy. No Boursin at home? Soft cream cheese with herbs will do.
- Milk: Makes the purée smooth. Whole milk adds extra creaminess, but semi-skimmed milk will also work.
- Salt: For flavor. If you use salted stock, add a little less salt.
- Shallots: They have a soft, sweet onion flavor that goes well with the minced meat. Red or regular onion will also work.
- Ground beef: You can also use half-and-half minced meat or minced chicken.
- Green beans: For a nice bite. Fresh beans are tasty, but frozen beans work just as well.
- Red pesto: For a spicy flavor. Green pesto is also possible, but that gives a different taste.
- Breadcrumbs: For a crispy crust. No breadcrumbs at home? Use crumbled rusks or panko.
Preparation
- Boil the peeled potatoes in stock until cooked. Drain and mash with a potato masher.
- Add the Boursin and milk and mix until creamy. Season with salt.
- Heat oil in a pan and fry the shallots until translucent. Add the minced beef and fry until crumbly. Add the green beans and red pesto and stir everything well. Spoon the mixture into the bottom of an oven dish.
- Distribute the mashed potatoes over the ground beef and smooth the top. Sprinkle breadcrumbs over the mash and bake the dish for 20 minutes at 390 °F (200 °C). Serve immediately.
