Ingredients for Bavette Steak Garlic Sauce
Okay, let’s gather everything you’ll need – I promise this isn’t one of those recipes with a million obscure ingredients! Here’s your shopping list:

- 10 ounce Bavette steak – look for nice marbling
- 12 ounce Yukon Gold potatoes, diced into ½-inch cubes
- 6 ounce asparagus, woody ends snapped off
- 1 large clove garlic – yes, whole!
- 4 tablespoon sour cream – full fat for maximum creaminess
- 1 packet beef demi-glace (about 1 oz) – the sauce’s secret weapon
- ¼ ounce fresh chives, thinly sliced
- 2 tablespoon butter, divided – because butter makes everything better
- Olive oil & vegetable oil – for roasting and searing
- Salt & pepper – freshly ground, please!
Ingredient Notes & Substitutions
No demi-glace? No panic! You can use 1 tablespoon Worcestershire sauce mixed with ¼ cup beef broth instead – it won’t be quite as rich, but still delicious. For my lactose-free friends, swap the sour cream with dairy-free yogurt and use vegan butter. Can’t find bavette? Flank steak works beautifully too – just slice it extra thin against the grain. And if you’re garlic-obsessed like me, feel free to roast 2 cloves – that roasted garlic paste is liquid gold in this recipe!
Equipment Needed for Bavette Steak Garlic Sauce
You probably already have everything you need for this recipe – that’s the beauty of it! Here’s your quick checklist:
- Baking sheet – for roasting our garlic and asparagus
- Aluminum foil – to make that little garlic roasting packet
- Large pot – for boiling the potatoes (a medium one works too in a pinch)
- Heavy-bottomed pan – cast iron or stainless steel for the perfect steak sear
- Mixing bowl – just a small one for mashing that roasted garlic
See? Nothing fancy – just good, basic tools that help create something extraordinary.
How to Make Bavette Steak Garlic Sauce
Alright, let’s break this down step-by-step – trust me, it’s easier than it looks! I’ll walk you through each part so everything comes together perfectly at the end. The key is timing – we’ll multitask like pros while that heavenly garlic roasts.

Preparing the Garlic and Asparagus
First, let’s get that garlic roasting – this is where the magic starts! Take your whole garlic clove (no need to chop) and place it on a small square of foil. Drizzle with olive oil, sprinkle with salt and pepper, then wrap it up into a little foil packet – like a garlic present! Pop it in a 400°F oven for 15 minutes alone, then add your trimmed asparagus to the same baking sheet. Toss the asparagus with oil, salt, and pepper, then roast everything together for another 10-12 minutes. You’ll know it’s done when the garlic is soft as butter and the asparagus tips are just starting to crisp.
Cook the Bavette Steak
While those roast, let’s tackle the steak. Here’s my golden rule: always pat your steak super dry with paper towels first – this gives you that perfect crust! Season generously with salt and pepper. Heat a drizzle of vegetable oil in your pan over medium-high until it shimmers, then add the steak. Don’t touch it for 5-7 minutes per side (less if you like it rare). When it’s done, transfer it to a cutting board and let it rest for at least 5 minutes – I know it’s tempting to cut right in, but this keeps all those juicy flavors locked in!
Making the Garlic Sauce
Now for the star of the show – that luscious garlic sauce! Carefully unwrap your roasted garlic (it’ll be hot!) and mash it into a paste with a fork. In the same pan you cooked the steak (with all those tasty brown bits), melt 1 tablespoon butter over medium heat. Add the garlic paste (start with half if you’re sensitive to garlic) and let it sizzle for just 1 minute to wake up the flavors. Pour in the demi-glace and ¼ cup water, simmering until it thickens slightly – about 2 minutes. Finish by swirling in another tablespoon of butter and any resting juices from the steak. Taste and adjust seasoning – this sauce should be rich, glossy, and packed with garlicky goodness!

Irresistible Bavette Steak with 10-Minute Garlic Sauce
A delicious Bavette Steak with Garlic Sauce served with creamy mashed potatoes and roasted asparagus. Perfect for a hearty and flavorful meal.
- Total Time: 45 mins
- Yield: 2 servings 1x
Ingredients
- 12 ounce Yukon Gold Potatoes
- ¼ ounce Chives
- 6 ounce Asparagus
- 1 clove Garlic
- 4 tablespoon Sour Cream (Contains: Milk)
- 10 ounce Bavette Steak
- 1 unit Beef Demi-Glace (Contains: Milk)
- 1 tablespoon Olive Oil
- 1 teaspoon Vegetable Oil
- 2 tablespoon Butter (Contains: Milk)
- Salt
- Pepper
Instructions
- Adjust rack to middle position and preheat oven to 400 degrees. Wash and dry all produce. Dice potatoes into ½-inch pieces. Thinly slice chives. Trim and discard woody bottom ends from asparagus. Peel garlic; place whole clove in the center of a small piece of foil; drizzle with olive oil and season with salt and pepper. Cinch into a packet.
- Place foil packet with garlic on a baking sheet. Roast on middle rack for 15 minutes, then add asparagus to same sheet. Carefully toss with a large drizzle of olive oil, salt, and pepper. Return to oven until garlic is softened and asparagus is browned and tender, 10-12 minutes more.
- Meanwhile, place potatoes in a large pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender when pierced with a fork, 15-20 minutes. Reserve ½ cup potato cooking liquid, then drain. Return potatoes to pot; mash until smooth. Stir in sour cream, half the chives, salt, and pepper. Add reserved potato cooking liquid a splash at a time as needed until potatoes are creamy. Keep covered off heat until ready to serve.
- While potatoes cook, pat steak very dry with paper towels; season with salt and pepper. Heat a drizzle of oil in a large pan over medium-high heat. Add steak and cook to desired doneness, 5-7 minutes per side. Turn off heat; transfer to a cutting board to rest. Wipe out pan.
- Once garlic is done, carefully transfer to a cutting board and mash with a fork until smooth. Melt 1 TBSP butter in pan used for steak. Add garlic (start with half and add more to taste); cook for 1 minute. Add demi-glace and ¼ cup water. Simmer until slightly thickened, 1-2 minutes. Turn off heat. Stir in another 1 TBSP butter and any resting juices from steak. Season with salt and pepper.
- Slice steak against the grain. Divide potatoes, asparagus, and steak between plates. Top steak and potatoes with sauce. Garnish with remaining chives and serve.
Notes
- For a richer sauce, add more butter to taste.
- Let the steak rest for 5 minutes before slicing to retain juices.
- Adjust garlic amount in the sauce based on your preference.

Tips for Perfect Bavette Steak Garlic Sauce
Here’s my hard-earned kitchen wisdom for steak night success: First, never skip resting your steak – those 5 minutes make all the difference between juicy and dry. For the garlic sauce, start with half the roasted garlic, then taste and add more – roasted garlic is mellow but potent! If your sauce seems thin, let it simmer another minute or two (it thickens as it cools too). And my secret? Toss in an extra pat of butter at the end for a glossy, restaurant-worthy finish. Oh, and save those steak drippings – they’re liquid gold for flavor!

Serving Suggestions for Bavette Steak Garlic Sauce
Oh my, wait till you see this beauty plated up! I always serve this steak draped in that glossy garlic sauce over a cloud of creamy mashed potatoes – the way the sauce seeps into the potatoes? Heaven! The roasted asparagus adds that perfect crisp-tender bite on the side. For wine lovers, a bold Cabernet Sauvignon makes magic with the garlicky richness. Feeling fancy? Swap asparagus for roasted mushrooms or charred broccolini – but keep those mashed potatoes, they’re non-negotiable in my book!
Storage & Reheating Instructions
Leftovers? No problem! Store everything in airtight containers in the fridge for up to 3 days. When reheating, go gentle – microwave the steak at 50% power in 30-second bursts to prevent toughness. For the mashed potatoes, stir in a splash of milk before reheating. The garlic sauce might thicken when cold – just warm it slowly in a pan with a teaspoon of water, stirring until silky again. Pro tip: asparagus is best eaten fresh, but if you must reheat, do it quick in a hot pan to keep some crunch!
Nutritional Information for Bavette Steak Garlic Sauce

Remember: These are estimates – your exact numbers might dance a bit depending on ingredient sizes and how generous you are with that glorious garlic butter sauce!
Frequently Asked Questions
Got questions? I’ve got answers! Here are the most common things people ask me about this bavette steak with garlic sauce recipe:
Can I Use a Different Cut of Steak?
Absolutely! While bavette steak has that perfect balance of tenderness and beefy flavor, flank or skirt steak make great substitutes. Just remember – these cuts are a bit chewier, so slice them thin against the grain after resting. Sirloin flap works well too if you can find it!
How Do I Adjust the Garlic Flavor?
Roasted garlic is milder than raw, but I get it – garlic love is personal! Start with half the roasted clove in your sauce, then taste and add more. For garlic-lovers, roast 2 cloves instead of one. Too strong? Add an extra pat of butter to mellow it out.
Can I Make the Sauce Ahead?
You sure can! Make the garlic sauce up to 2 days ahead – just store it in the fridge (it’ll thicken when cold). When ready to serve, gently reheat it in a pan with a splash of water, stirring until silky smooth again. Pro tip: wait to add the final butter until reheating for maximum freshness.
