Yellow Heirloom Tomato Sauce Recipe from The Farm at Glenwood Mountain

Every now and then, you stumble upon a dish so simple yet so extraordinary that it stops you in your tracks. That’s exactly what happened to me at The Farm at Glenwood Mountain. During my visit (where Highland cows casually strolled the pastures and Chef-led dinners showcased the best of the season), I tasted a silky, sun-bright Yellow Heirloom Tomato Sauce that left me absolutely speechless.

The sauce, crafted by Chef Steve MacLean, was unlike any red sauce I’d ever tried. Sweet, mellow, and kissed with just the right balance of garlic, onion, and fresh basil—it felt like summer captured in a spoonful. I was so blown away, I had to get my hands on the recipe and recreate it at home.

Lucky for us, Chef Steve was generous enough to share his secret. And trust me—you’ll want to make this one before yellow tomato season slips away.

Why Yellow Tomatoes?

 

While red tomatoes are the go-to for sauces, yellow heirlooms bring a unique character to the table. They’re less acidic, slightly fruity, and lend the sauce a gorgeous golden hue that looks as inviting as it tastes. Combined with slow-cooked onions, garlic, and the fragrance of just-picked basil, the result is a sauce that’s bright, silky, and layered with flavor.

How to Use Yellow Tomato Sauce

This isn’t just a pasta sauce (though it makes spaghetti feel like a special occasion). It’s versatile and shines in all sorts of dishes:

• Spoon it over grilled fish or chicken.
• Add a little cream and make it a delicious soup.
• Drizzle over fresh mozzarella or burrata with crusty bread.
• Freeze a batch now to enjoy that farm-fresh flavor all winter long.

I first tried this tomato sauce at dinner on The Farm at Glenwood Mountain, and I was so blown away by it that I purchased some that night from their store. Since the farm is a 2-hour drive for me, I begged them for the recipe. I'm so obsessed with this sauce, I've already ordered two seed catalogs to source yellow tomato seeds for next year.

Ingredients

• 2 lbs. heirloom yellow tomatoes
• 1 large yellow onion, thinly sliced 
• 4 cloves garlic, thinly sliced
• 3 tbsp extra virgin olive oil
• 2 tsp sea salt or to taste 
• 1 tsp of freshly cracked black pepper 
• 1 large bunch of basil leaves, tied together with kitchen string

Instructions

1. Bring a large pot of water to a boil to blanch the tomatoes. 
2. While water is coming to a boil, score a small “X” on the bottom of the tomatoes. 
3. Fill a large bowl with ice and water, and set aside for cooling tomatoes after blanching. 
4. Blanch the scored tomatoes in the boiling water for 30-60 seconds, then transfer to the ice bath to cool.
5. Once the tomatoes are cool enough to handle, peel the skins off starting where the “X” is marked.
6. Cut the peeled tomatoes in half, core them and remove the seeds, then roughly chop the flesh.
7. In a wide saucepan or Dutch oven, heat olive oil over medium-low heat.
8. Add the onion, salt, and pepper to the pan and cook gently for 6-8 minutes, until the onions are soft and translucent but not browned. 
9. Add the sliced garlic and cook for 1-2 minutes, just until the garlic is fragrant. 
10. Stir in the chopped yellow tomatoes and the bunch of basil.
11. Lower the heat to a gentle simmer and cook uncovered for 30-40 minutes, stirring occasionally until the sauce has thickened and the tomatoes have broken down. 
12. Remove the bunch of basil and discard.
13. For a smooth sauce, use an immersion blender or transfer the sauce to a blender and puree. Pass the blended sauce through a fine-mesh strainer, adjust seasoning as needed, and enjoy.
