What Type of Onions Should I Use for Easy Onion Gravy?

You can honestly use any kind of onion you have on hand, but I find that yellow onions give the best balance of sweetness and savoriness. They caramelize beautifully and develop a rich, deep flavor without overpowering the gravy. If you prefer a slightly sweeter gravy, Vidalia or sweet onions work wonderfully too. White onions will give you a sharper edge, while red onions lend a bit of color and complexity, though they may slightly alter the hue of your gravy.

Options for Substitutions

This gravy is super flexible, and I’ve swapped ingredients out a few times depending on what I had in my kitchen. Here are some great alternatives if you need them:

• Butter: Use olive oil or vegan butter for a dairy-free option.
• All-purpose flour: Cornstarch or gluten-free flour blends also work for thickening.
• Beef broth: Use vegetable broth for a vegetarian version, or chicken broth for a lighter flavor.
• Fresh herbs: If you’re out, dried thyme or rosemary will do—just reduce the quantity since dried herbs are more concentrated.
• Balsamic vinegar: A splash at the end adds depth if you’re skipping Worcestershire sauce.

Ingredients for This Easy Onion Gravy

• Yellow Onions – The star of the show. They caramelize into soft, golden perfection and create the sweet-savory base of the gravy.
• Unsalted Butter – Used to sauté the onions and add richness to the final sauce. If you’re going dairy-free, swap it for olive oil or a plant-based butter.
• All-Purpose Flour – This is your thickener. It binds the butter and onion mixture into a roux that gives the gravy its luscious, silky texture.
• Beef Broth – Adds a deep, savory flavor that complements the onions perfectly. You can use vegetable broth for a vegetarian version.
• Worcestershire Sauce – A dash of this amps up the umami and gives the gravy that classic savory punch.
• Garlic Powder – A subtle background note that brings everything together.
• Salt and Black Pepper – Seasoning is key. These balance the sweetness of the onions and round out the flavor.
• Fresh Thyme (Optional) – Adds a delicate herby aroma if you want a little extra dimension.

Step 1: Slice and Sauté the Onions

Thinly slice your yellow onions. In a large skillet or saucepan, melt the butter over medium heat. Add the onions and cook, stirring frequently, until they’re soft and golden brown—this should take about 15–20 minutes for a nice caramelization.

---

Step 2: Make the Roux

Once the onions are caramelized, sprinkle in the flour and stir to coat the onions evenly. Cook for about 2–3 minutes, stirring constantly to cook off the raw flour taste. This roux is what gives the gravy its signature thickness.

---

Step 3: Pour in the Broth

Slowly pour in the beef broth while whisking to prevent lumps. Keep whisking until the flour is fully dissolved and the mixture starts to smooth out.

---

Step 4: Simmer and Season

Add in the Worcestershire sauce, garlic powder, salt, and black pepper. Let the gravy simmer for 5–7 minutes, stirring occasionally, until it thickens to your desired consistency. If it gets too thick, just add a splash more broth.

---

Step 5: Add Final Touches

Optional: stir in a few fresh thyme leaves for an herby finish. Taste and adjust seasoning as needed. Once it’s perfectly flavorful and silky, it’s ready to pour over whatever your heart desires.

How Long to Cook the Easy Onion Gravy

The entire process takes about 30 minutes from start to finish. The most time-consuming part is caramelizing the onions, which takes around 15–20 minutes to get that rich, golden-brown flavor. Once that’s done, the roux and simmering steps move quickly, adding only another 10 minutes or so.

Tips for Perfect Easy Onion Gravy

• Don’t rush the onions – Low and slow is key to unlocking their natural sweetness. High heat will burn them instead of caramelizing.
• Whisk constantly when adding broth – This keeps your gravy lump-free and silky smooth.
• Use warm broth – Pouring in warm (not cold) broth helps the roux dissolve more evenly and speeds up thickening.
• Season gradually – Add salt and pepper in stages and taste as you go. Broth and Worcestershire sauce already contain salt.
• Thin it if needed – If the gravy thickens too much as it cools, just add a splash of broth or water before serving and give it a quick stir.

---

Watch Out for These Mistakes While Cooking

• Burning the onions: This happens if you cook them on high heat or don’t stir often enough. Keep the heat medium to medium-low and be patient.
• Skipping the roux step: The flour needs time to cook in the butter—don’t rush it or you’ll get a pasty, raw flour taste.
• Adding cold broth: Cold liquid can cause lumps in your gravy. Warm it slightly before adding.
• Over-salting: Between the broth and Worcestershire, there’s already salt. Always taste before adding more.
• Letting it sit too long without stirring: Gravy thickens quickly and can develop a film or scorch on the bottom if left unattended.

Storage Instructions

Let the gravy cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to 4 days. When you’re ready to use it again, just reheat it in a saucepan over medium heat, stirring frequently. If it thickens too much in the fridge, add a little water or broth while reheating to loosen it up.

For longer storage, you can freeze the gravy for up to 2 months. Let it thaw overnight in the fridge, then warm it gently on the stove. The texture may change slightly after freezing, but a good stir and a splash of liquid will bring it back to life.
