Canonical URL: https://www.topshelf.recipes/recipes/labour-day-grilled-foil-pack-frittatas-charred-corn-heirloom-tomatoes-basil ## Author Jake Woods https://www.topshelf.recipes/chef/jake-woods Published: August 3, 2026 Last Updated: September 3, 2026 ## About This Recipe This foil-pack grilled frittata was born from the desire to make brunch portable without sacrificing the charred, sweet summer flavors that only a hot grill can deliver. Individual packets let each portion puff and set in its own little oven, trapping smoky corn kernels, blistered heirloom tomato juices and melted sharp cheddar together into a tender, sliceable egg custard. The contrast is what sells it: bright basil and tomatoes cut through the richness of eggs and cheese, while charred corn adds a caramelized pop that reads as both rustic and celebratory on a Labour Day morning. The method is intentionally forgiving — two-zone heat gives you the best of both worlds (sear then gentle finish), and the packets make it easy to prep ahead, transport to a cookout and reheat without fuss. This version is for hosts who like to mingle instead of babysit a griddle: assemble in the morning, hit the grill when guests arrive, and let each packet hold its warmth. Small technique choices — removing excess tomato liquid, using heavy-duty foil and cracking eggs at room temperature — keep the texture reliably silky and not watery, so you get a party-ready brunch with minimal cleanup. ## Recipe Information - Prep Time: 20 minutes - Cook Time: 18 minutes - Total Time: 38 minutes - Servings: 6 - Difficulty: Easy - Category: Grilling ## Ingredients ### Preheat grill and char the corn & tomatoes - 3 ears Fresh sweet corn (on the cob) - 2 medium Heirloom tomatoes (medium) - 1 tbsp Extra-virgin olive oil - 1 tsp Kosher salt - 1/2 tsp Freshly ground black pepper ### Whisk eggs and assemble foil packs - 8 large Large eggs - 1/3 cup Whole milk - 1 cup Sharp cheddar, shredded - 4 sheets Heavy-duty aluminum foil (12 x 12 in. sheets) ### Remove kernels, dice tomatoes and chop basil - 1/4 cup Fresh basil, packed and chopped ## Instructions ### 1. Preheat grill and char the corn & tomatoes Set up a two-zone fire: one side hot/direct (about 500°F / 260°C) and one side indirect/lower (about 350°F / 175°C). Brush corn and halved tomatoes with olive oil and season lightly with kosher salt and pepper. Place the corn and tomatoes cut-side down on the hot side and char: rotate corn every few minutes until evenly blackened in spots (about 8–10 minutes total); tomatoes need 2–4 minutes per side until blistered and charred. Move charred veg to the cooler side to stop cooking and cool slightly. ### 2. Remove kernels, dice tomatoes and chop basil When cool enough to handle, cut the kernels off the cobs into a bowl and roughly dice the charred heirloom tomatoes, discarding excess liquid if desired. Chop the basil and reserve a small handful for garnish. Taste the corn and tomatoes and adjust seasoning with a pinch more salt or pepper if needed. ### 3. Whisk eggs and assemble foil packs In a large bowl whisk together the eggs and milk until blended. Stir in the charred corn kernels, diced tomatoes, shredded cheddar and chopped basil. Lay out 4 sheets of heavy-duty foil (about 12 x 12 in.), divide the mixture evenly among them (about 1/4 of the mixture per sheet), fold foil up around the mixture leaving a small vent, and crimp edges to form a loose packet that will puff as the frittata cooks. ### 4. Cook the foil-pack frittatas on the grill Place the sealed packets seam-side up on the indirect side of the grill and cook until the eggs are set when gently squeezed and no longer liquid in the center, about 12–15 minutes. For a touch of extra char and to set edges, open the packets and place them briefly over direct heat for 1–2 minutes, watching carefully to avoid burning. Use a thermometer if desired — set eggs register about 160°F (71°C). ### 5. Rest, garnish, and reheating notes Let packets rest 2 minutes, then open carefully (steam will be hot) and garnish with reserved basil and an extra sprinkle of cheddar if you like. To make ahead: prepare through Step 3, refrigerate up to 24 hours, then grill from chilled for 15–18 minutes; to reheat cooked packs, place sealed packets on the indirect grill or in a 350°F oven for about 8–10 minutes until warmed through. ## Nutrition Estimated nutrition per serving (1 foil-pack frittata (about 220g)): - Calories: 292 kcal - Protein: 16.4 g - Carbohydrates: 37.3 g - Fat: 10.4 g - Saturated Fat: 4.6 g - Trans Fat: 0.2 g - Fiber: 4.8 g - Sugar: 0.1 g - Added Sugars: 0 g - Cholesterol: 23 mg - Sodium: 453 mg - Potassium: 447 mg - Calcium: 174 mg - Iron: 1.1 mg - Vitamin D: 0.2 mcg ## Tips ### Give the corn space Char the ears directly over high heat and rotate frequently so kernels blister without steaming; dry them briefly after cutting off the cob to avoid watering down the eggs. ### Control tomato moisture Spoon or blot excess liquid from the charred tomato halves before adding them to the egg mix to prevent soggy packets and a runny center. ### Leave room to puff Form packets loosely and leave a small vent — eggs expand as they cook and need air circulation to set evenly without bursting the foil. ### Finish with direct heat If edges need more color, open the packets and place briefly over direct heat for 1–2 minutes, watching closely to avoid charring the eggs themselves. ### Use a thermometer For consistent results, aim for an internal temperature of about 160°F (71°C); it’s the safest way to know the center is set without overcooking the edges. ## Variations and Substitutions ### Bacon or chorizo boost Stir in 4–6 ounces of cooked, crumbled bacon or chopped cooked chorizo for a smoky, savory punch; precook the meat so packets don't become greasy from raw renderings. ### Feta, olive & oregano Swap sharp cheddar for crumbled feta and add chopped kalamata olives and a pinch of dried oregano for a tangy Mediterranean spin that stands up to the charred corn. ### Dairy-free / vegan option Replace eggs with a chickpea-flour batter (1 cup chickpea flour + 1 cup water + pinch of baking powder) and use a vegan cheese; bake a little longer and expect a denser texture. ### Late-summer veggie swap If corn is scarce, substitute diced grilled zucchini and bell pepper for a different, yet equally charred, vegetable profile that pairs nicely with basil. ## Notes These single-serving foil-pack frittatas are perfect for a laid-back Labour Day morning at the grill — bright, portable and forgiving. Make them ahead and warm on the grill so everyone can eat whenever they're ready. ### Storage and Make-Ahead Store cooled, sealed foil packets or transfer frittatas to an airtight container in the fridge for up to 3–4 days. To reheat, place sealed packets on the indirect grill or in a 350°F oven until warmed through (8–10 minutes chilled, slightly longer from refrigerated). You can freeze fully cooked packets up to one month; thaw overnight in the fridge before reheating to preserve texture. ### Serving Suggestions Serve these packets hot from the foil with a handful of peppery arugula tossed in lemon vinaigrette and some grilled baby potatoes or crusty bread to soak up juices. For drinks, a smoky Bloody Mary or an effervescent sparkling rosé matches the char and bright tomato notes; for a nonalcoholic choice, iced coffee or a citrusy sparkling water is refreshing. ## Frequently Asked Questions ### Can I assemble the packets the night before? Yes — complete through Step 3 and refrigerate sealed packets up to 24 hours. Grill straight from chilled, adding a few minutes to the cooking time so the centers reach 160°F (71°C). ### What if my tomatoes release too much liquid? After charring, let tomatoes rest cut-side down briefly and blot with a towel or spoon off excess juices before dicing; this prevents the eggs from becoming overly watery. ### Can I bake these in the oven instead of grilling? Absolutely — bake sealed or in a oven-safe dish at 350°F (175°C) for about 18–22 minutes, then open and broil 1–2 minutes if you want a little extra color on top. ### How do I know when the frittatas are done? Gently press the top of a packet; it should feel set with only a slight give, or use an instant-read thermometer aiming for 160°F (71°C) in the center. ### Is heavy-duty foil necessary? Yes — heavy-duty foil prevents leaks and punctures from knife points or edges, and it insulates better so packets cook evenly without scorch spots. ## Related Recipes and Guides - [Tandoori Yogurt Marinated Grilled Chicken (Tandoori Style on the Grill)](https://www.topshelf.recipes/recipes/tandoori-yogurt-marinated-grilled-chicken) - [Labor Day Grilled Lobster Rolls with Charred Scallion Brown Butter & Lemon‑Herb Aioli](https://www.topshelf.recipes/recipes/labour-day-grilled-lobster-rolls-charred-scallion-brown-butter-lemon-herb-aioli) - [Bulgogi Smash Burger](https://www.topshelf.recipes/recipes/bulgogi-smash-burger) - [Campfire‑Smoked Potato Salad with Mustard‑Bacon Vinaigrette — A Labor Day Grilling Side for Steak](https://www.topshelf.recipes/recipes/campfire-smoked-potato-salad-mustard-bacon-vinaigrette) - [Hanger Steak with Shallot Sauce](https://www.topshelf.recipes/recipes/hanger-steak-with-shallot-sauce) - [Grilled Pineapple Upside-Down Cake](https://www.topshelf.recipes/recipes/grilled-pineapple-upside-down-cake) - [Outdoor Food Safety 101](https://www.topshelf.recipes/articles/outdoor-food-safety-101) - [Labor Day Grill Care](https://www.topshelf.recipes/articles/labour-day-grill-care) - [Trending Labor Day Steak Finishes](https://www.topshelf.recipes/articles/trending-labor-day-steak-finishes)
