Ingredients
Full ingredients and substitutions are in the recipe box below.
- Yellow onions: The star of this recipe. They become sweet and deeply flavorful as they caramelize. White onions work well too, while sweet onions make the dish even milder.
- Extra virgin olive oil: Helps soften and caramelize the onions while adding richness. Avocado oil is a good substitute.
- Salt: Brings out the onions’ natural sweetness and seasons the dish throughout cooking.
- Sugar: A small amount helps the onions caramelize faster. You can skip it if you prefer—the onions may just need a few extra minutes to become soft and golden. Brown sugar or maple syrup work too.
- Balsamic vinegar: Adds tangy depth and helps build that classic caramelized onion beans flavor. Apple cider vinegar or red wine vinegar are excellent alternatives.
- Garlic: Fresh grated or pressed garlic blends beautifully into the broth. If you’re sensitive to garlic, simply leave it out or use garlic-infused olive oil for a gentler flavor.
- Vegetable broth: Creates a rich, savory base. Use low-sodium broth so you can season to taste.
- Butter beans: Creamy, hearty, and packed with fiber and plant-based protein. Cannellini beans or Great Northern beans are great substitutes, making this an equally delicious butter beans with parmesan dinner.
- Dried thyme: Adds earthy flavor. Herbes de Provence or dried oregano work just as well.
- Parmesan: Stirred in at the end for savory richness. Pecorino Romano or a vegetarian hard cheese are tasty alternatives.
- Crusty bread: Perfect for soaking up the onion broth. A baguette, sourdough, or country loaf all pair beautifully with this cozy vegetarian dinner.
How to Make French Onion Butter Beans
Step 1. Caramelize the onions
Peel the onions, cut them in half, and slice them about ⅙ inch (4 mm) thick.
Heat the olive oil in a large 12-inch (30 cm) skillet over medium heat. Add the onions, salt, and sugar, then cook for 5 minutes, stirring often.
Pour in the water and reduce the heat to medium-low. Cook for about 20 minutes, stirring occasionally, until the water has evaporated and the onions are soft and golden.
Increase the heat to high, add the balsamic vinegar, and cook for 2 minutes, stirring often. This quick method gives the French onion beans plenty of rich, caramelized flavor without an hour of cooking.
Step 2. Add the beans and broth
Stir in the grated or pressed garlic and cook for 30 seconds, just until fragrant.
Pour in the vegetable broth, then add the drained butter beans, dried thyme, and black pepper.
Bring everything to a gentle simmer and cook uncovered for 10 minutes. The broth will reduce slightly while the beans absorb the savory onion flavor.
Step 3. Finish with Parmesan
Turn off the heat and let the skillet rest for about 1 minute, or until the broth stops bubbling.
Add the finely grated Parmesan and stir gently until it blends into the broth and makes it lightly creamy.
Waiting for the bubbling to stop is important. If the skillet is too hot, the Parmesan can become stringy instead of smooth.
Taste and add more salt or black pepper if needed.
Step 4. Serve
Bring this one-pan vegetarian dinner straight to the table while it is still warm.
Serve it with toasted baguette slices, sourdough, or another crusty bread for scooping up the butter beans and rich onion broth.
Tips
- Trust the quick caramelizing method: The combination of salt, sugar, water, and vinegar creates deeply flavorful onions in about 30 minutes, so there’s no need to stand over the stove for an hour.
- Use a large skillet: A 12-inch (30 cm) skillet gives the onions enough room to caramelize instead of steam.
- Choose low-sodium vegetable broth: Parmesan adds plenty of saltiness, so starting with a lighter broth lets you season the dish to taste.
- Mash a few butter beans: Press a handful of the beans with the back of your spoon during the last few minutes of cooking for a naturally creamier broth—no flour or cream needed.
- Let the bubbling stop before adding Parmesan: Remove the skillet from the heat and wait about 1 minute. If the broth is still simmering, the Parmesan can become stringy instead of blending into a creamy, silky broth.
- Grate the Parmesan yourself: A block of Parmesan grated with a fine grater melts much more smoothly into the broth than pre-grated Parmesan from a packet. The packaged kind still works and tastes delicious, but the texture won’t be quite as silky.
- Toast the bread: A crisp baguette or sourdough holds up better in the broth and adds the classic French onion experience.
- The leftovers get even better: The onions continue to infuse the broth as it sits, making this an excellent make-ahead meal. Store leftovers in the refrigerator for up to 4 days, and reheat gently on the stovetop. Toast fresh bread just before serving.
