Classic Beef Stroganoff Garlic Mash

This comforting Beef Stroganoff with Roasted Garlic Mash is my favorite dinner to make when the weather turns chilly. The velvety sauce comes together quickly in one pan and makes even ordinary weeknights feel special thanks to buttery potatoes flecked with sweet roasted garlic. While classic on the table, there is nothing old-fashioned about the way your kitchen will smell while it simmers.

The first time I made this stroganoff for friends they thought it tasted better than anything from a nice bistro. Now I pull it out any time we want a little comfort and nostalgia without too much fuss.

Ingredients

• Beef sirloin or ribeye steak: Choose well-marbled cuts for tender juicy strips
• Cremini or white mushrooms: select mushrooms with tight caps for the best earthy flavor
• Yellow onion: gives sweetness and depth to the sauce
• Fresh garlic: for both roasted mash and sautéing into the sauce creamy when roasted pungent when sautéed
• Sour cream: Real full-fat adds lushness and tang to the stroganoff
• Dijon mustard: brightens the dish with subtle heat
• Worcestershire sauce: rounds out the meaty flavors
• Beef broth: Use low sodium for more control over the seasoning
• Unsalted butter: for sautéing and for mashing potatoes rich flavor is key
• Russet potatoes: High-starch makes ultra-creamy mashed potatoes
• Whole milk or heavy cream: for the mash adds silkiness
• Fresh parsley: for sprinkling over just before serving and gentle freshness
• Fine sea salt and freshly ground black pepper: the quality makes a real difference in every bite

Instructions

Roast the Garlic:

Cut the top from a whole head of garlic and drizzle with a bit of olive oil. Wrap tightly in foil and bake at 400°F for around thirty five minutes until the cloves are buttery and caramelized. This slow roasting makes the mash sweet and fragrant.

Prepare the Potatoes:

Peel and cube the potatoes. Place in a pot of salted cold water and bring to a gentle boil. Cook until fork tender about fifteen to twenty minutes then drain well. Warm the milk or cream and mash together with roasted garlic and butter until smooth. Season to taste and keep warm covered.

Brown the Beef:

Slice steak into half inch strips against the grain for tenderness. Pat dry and season generously with salt and pepper. Melt butter in a heavy skillet over medium high heat and sear the beef in batches to ensure a caramelized crust. Remove just when browned so it stays juicy.

Sauté the Vegetables:

In the same pan drop in more butter if needed and sauté sliced onion and mushrooms over medium low heat. Cook for about eight to ten minutes scraping up all the beef bits from the bottom. Layering flavors here is what takes the sauce over the top.

Build the Stroganoff Sauce:

Stir in minced garlic until fragrant then whisk in mustard and Worcestershire sauce. Pour in the beef broth and bring everything up to a gentle simmer letting it reduce slightly which concentrates the flavor.

Finish with Sour Cream:

Turn off the heat and fold in the sour cream. This prevents curdling. Return the beef and any juices to the skillet stirring gently to coat everything in the sauce. Taste for seasoning.

Serve:

Pile the roasted garlic mash on plates and spoon the stroganoff on top. Garnish everything with chopped fresh parsley for a pop of color and herbal lift.

Save to Pinterest

There is nothing I love more than roasted garlic in mashed potatoes. The kids always fight over who gets the spoon to scrape the bowl. My youngest asked if they could have the mash even without the stroganoff which is always a good sign.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to three days. To reheat gently warm the stroganoff in a pan over low heat and add a splash of broth if needed. The mashed potatoes are best revived with a bit of extra cream mixed in before warming.

Ingredient Substitutions

If you cannot find beef sirloin or ribeye substitute with tenderloin or even ground beef for a weeknight option. Greek yogurt works if you are out of sour cream. Baby bella mushrooms or even portobello caps can be used for a more robust flavor.

Serving Suggestions

Serve over wide egg noodles or steamed rice if you run out of potatoes. Pair with buttery green beans or a crisp green salad to balance the richness. For a special twist add a side of pickled cucumbers to cut through the creamy sauce.

Cultural and Historical Notes

Beef Stroganoff originated in Russia in the nineteenth century as aristocratic fare. The version with mushrooms and sour cream became known in the West after World War Two when it became an American dinner table staple. Every family has a secret to the sauce but the charm is always in the tender beef and creamy tang.

Seasonal Adaptations

Use spring onions or chives when in season for brighter flavor Try wild mushrooms from the farmers market in early fall Swap mashed sweet potatoes in autumn when they are abundant

Success Stories

My neighbor made this for their holiday party and it was the first platter finished. One reader sent a photo of her kids licking the plate clean and said it is the only way she gets them to eat mushrooms. I have made it for family reunions and it always brings out happy sighs and stories about grandma’s kitchen.

Freezer Meal Conversion

To freeze make the stroganoff completely and cool fully before storing in a heavy freezer bag or container. Reheat gently on the stovetop with a bit of broth. While mashed potatoes can be frozen they turn out best when made fresh just before serving.
