Basic Onion Gravy Recipe

This recipe is designed to be simple, but it provides a strong foundation for anyone looking to create homemade gravy from scratch. The ingredients are minimal, and the steps are straightforward, making it perfect for home cooks of any level.

Ingredients:

Ingredient	U.S. Measurement	Metric Measurement
Yellow onions	2 large	400 g
Butter	4 tbsp	60 g
Olive oil	1 tbsp	15 mL
Flour (all-purpose)	2 tbsp	16 g
Beef broth (or vegetable for vegetarian option)	2 cups	480 mL
Worcestershire sauce (optional)	1 tsp	5 mL
Salt	To taste	To taste
Black pepper	To taste	To taste

Instructions:

1. Caramelize the onions —

• Start by slicing the onions thinly. Heat the butter and olive oil in a large skillet over medium heat.
• Add the onions and cook them slowly, stirring occasionally. Caramelization takes time—usually around 20-30 minutes—but this step is crucial for developing a deep, rich flavor.
• The onions should become soft and golden brown. If they begin to stick, you can add a splash of water to deglaze the pan.

1. Make a roux —

• Once the onions are caramelized, sprinkle the flour over them. Stir continuously for about 2 minutes to cook off the raw flour taste. This step helps to thicken the gravy.

1. Add broth —

• Gradually add the beef broth (or vegetable broth), stirring constantly to prevent lumps from forming. Bring the mixture to a simmer and allow it to cook for another 10 minutes, stirring occasionally, until the gravy thickens.

1. Season —

• Add salt and black pepper to taste. You can also add Worcestershire sauce at this stage for an extra umami kick.

1. Serve —

• Your onion gravy is now ready to serve! It can be poured over meats, mashed potatoes, or any dish that could benefit from a savory sauce.

Tips for Perfect Onion Gravy

• Take your time with the onions — The secret to truly flavorful onion gravy is giving the onions enough time to caramelize properly. This process can take up to 30 minutes, but the result is worth the wait.
• Use the right broth — Beef broth gives a rich and savory base for the gravy, but you can easily substitute vegetable broth for a vegetarian version.
• Deglaze the pan — After caramelizing the onions, you may find some brown bits stuck to the bottom of the pan. Don’t waste these flavorful bits—add a splash of broth or water to loosen them up, incorporating all that flavor into your gravy.

Variations and Add-Ons

Once you’ve mastered the basic onion gravy recipe, you can experiment with various ingredients and flavors to make it your own. Here are a few ideas to get you started:

1. Creamy Onion Gravy —

• Add ½ cup of heavy cream to the gravy at the end of cooking. The cream adds a luscious texture and softens the flavors of the caramelized onions.

2. Herb-Infused Gravy —

• Add fresh herbs like thyme or rosemary while the gravy simmers. This brings a fragrant, earthy note that complements roast meats or hearty vegetable dishes.

3. Mushroom and Onion Gravy —

• Sauté mushrooms along with the onions to create a heartier, more robust gravy. This variation pairs well with vegetarian dishes or alongside beef dishes.

4. Vegan Onion Gravy —

• To make this gravy vegan, swap the butter for a plant-based margarine or oil, and use vegetable broth instead of beef broth. Ensure that any Worcestershire sauce used is vegan, or leave it out.

5. Spiced Onion Gravy —

• Add a pinch of smoked paprika or cayenne pepper for a bit of spice. This works especially well for grilled meats or BBQ dishes.

How to Store and Reheat Onion Gravy

Onion gravy can be made ahead of time and stored for later use, making it a convenient option for busy weeknight meals.

• Storing — Let the gravy cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days.
• Reheating — Reheat the gravy on the stovetop over medium heat, stirring frequently. If the gravy has thickened too much in the fridge, you can add a bit of broth or water to thin it out.
• Freezing — You can freeze onion gravy for up to 3 months. To reheat, thaw it overnight in the refrigerator and then warm it on the stovetop.

Common Mistakes to Avoid

Even though onion gravy is simple to make, there are a few common pitfalls that can affect the final result. Avoid these mistakes to ensure your gravy turns out perfectly every time.

• Not caramelizing the onions long enough — If your onions are still pale after a few minutes, keep going! Proper caramelization can take up to 30 minutes but is essential for a deep flavor.
• Using too much flour — While flour helps thicken the gravy, using too much can result in a pasty texture. Stick to the recipe proportions to avoid this.
• Lumps in the gravy — To prevent lumps, always add the broth gradually, stirring constantly as you do so. This helps the flour blend smoothly into the liquid.
