Ingredients of the Glazed Yellow Squash With Onions
For the Vegetable Base
- 3 medium yellow summer squash, sliced into half-moons
- 1 large yellow onion, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter
For the Glaze
- 1/4 cup vegetable broth
- 1 tablespoon honey or maple syrup
- 1/2 teaspoon kosher salt
- 1/4 teaspoon cracked black pepper
- 1/4 teaspoon garlic powder

Equipment / Tools Needed
- Large non-stick skillet or heavy-bottomed frying pan
- Sharp chef’s knife
- Lidded container for storage
- Silicone spatula
- Cutting board
Step-by-Step Instructions
Step 1: Prepare the Ingredients
Start by washing the yellow squash thoroughly and drying it well. Trim the stem ends and slice each squash into half-moons about 1/4 inch thick. Peel the yellow onion and slice it into thin, uniform strips to ensure they cook evenly alongside the squash.
Step 2: Caramelize the Onions
Heat the olive oil and butter in your skillet over medium heat. Once the butter is melted and foaming, add the sliced onions. Sauté them for about 6 to 8 minutes, stirring occasionally, until they turn soft and develop a light golden brown color. This forms the flavor foundation for your glaze.
Step 3: Sauté the Squash
Add the sliced squash to the skillet with the onions. Increase the heat slightly to medium-high. Gently toss the vegetables with the onions, ensuring they are coated in the fat. Cook for 5 minutes until the squash develops a soft, tender texture and begins to take on a slightly vibrant, golden hue.
Step 4: Create the Glaze
Lower the heat to medium. Pour in the vegetable broth, honey or maple syrup, salt, pepper, and garlic powder. Stir everything gently to combine the liquids. Allow the mixture to simmer for another 3 to 4 minutes.
Step 5: Reduce and Serve
As the liquid simmers, it will reduce into a light, glossy syrup that clings to the vegetables. Toss the squash and onions carefully so they stay intact. Once the sauce has thickened and the squash is tender but not mushy, remove from the heat immediately to prevent overcooking.

Tips & Tricks
Always keep your squash slices uniform in thickness to ensure they finish cooking at the same time. If the pan looks dry during the glazing process, add a splash more broth to keep the sauce silky. For a deeper flavor, let the onions get a slightly darker brown color before adding the squash, as this increases the savory depth of the final dish.
Serving Suggestions
This dish pairs beautifully with roasted chicken or pan-seared white fish for a light, balanced dinner. It also makes a wonderful addition to a grain bowl featuring quinoa or farro. For a brighter finish, garnish with fresh chopped parsley or a squeeze of lemon juice just before serving.
Variations / Substitutions
- Add a pinch of red pepper flakes during the sauté phase for a gentle heat.
- Substitute yellow squash with zucchini for a more earthy flavor profile.
- Replace the honey with agave nectar if you prefer a different sweetness profile.
- Include sliced bell peppers to add extra color and a crisp, fresh crunch.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a skillet over low heat with a teaspoon of water, stirring gently until warmed through. Avoid microwaving if possible, as it can soften the squash too much, making it lose its appealing texture.

FAQ
Can I make this dish ahead of time?
Yes, you can prep the vegetables in advance by slicing them and keeping them in the fridge. However, for the best texture, cook the dish just before you plan to eat, as the squash releases water upon storage.
What is the best way to keep the squash from getting mushy?
The key is high heat during the initial sauté and avoiding over-stirring. Take the dish off the heat as soon as the squash is tender-crisp so it does not continue to soften in the residual heat of the pan.
Can I use butter instead of olive oil?
You can use a mix of both or just butter if you prefer a richer, more decadent glaze. Using a blend of oil and butter helps prevent the butter from burning while providing that classic depth of flavor.
Is this recipe suitable for freezing?
Freezing is not recommended for this specific dish. Squash has a high water content and will turn into a soft puree once thawed and reheated, losing the nice bite that makes this recipe special.
